- Practice Test 3 8. You draw a sample of size 30 from a normally distributed population with a standard deviation of four. What is the standard error of the sample mean in this scenario, rounded to two decimal places? What is the distribution of the sample mean? Round to two decimal places 7. Suppose the sample size in this study had been 50, rather than Round your answer to two decimal places. Comparing graphs of the standard normal distribution z-distribution and a t-distribution with 15 degrees of freedom df , how do they differ?
- Comparing graphs of the standard normal distribution z-distribution and a t-distribution with 15 degrees of freedom df , how are they similar? Use the following information to answer the next five exercises. Body temperature is known to be distributed normally among healthy adults. Because you do not know the population standard deviation, you use the t-distribution to study body temperature. You collect data from a random sample of 20 healthy adults and find that your sample temperatures have a mean of What is the degrees of freedom df for this study? Round to two decimal places. Suppose your sample size had been 30 rather than Round to two decimal places 8. You conduct a poll of randomly selected city residents, asking them if they own an automobile.
- Find the sample proportion and sample standard deviation for this data. Round to four decimal places. Use the following information to answer the next three exercises. You are planning to conduct a poll of community members age 65 and older, to determine how many own mobile phones. Use an estimated population proportion of 0. What sample size do you need? Suppose you knew from prior research that the population proportion was 0. What sample size would you need? Assume the population proportion is 0. In your state, 58 percent of registered voters in a community are registered as Republicans. You want to conduct a study to see if this also holds up in your community. State the null and alternative hypotheses to test this. You believe that at least 58 percent of registered voters in a community are registered as Republicans.
- You believe that the mean household value in a particular neighborhood is lower than the city average. Write the null and alternative hypotheses to test this. If you reject H0 when H0 is correct, what type of error is this? If you fail to reject H0 when H0 is false, what type of error is this? What is the relationship between the Type II error and the power of a test? A new blood test is being developed to screen patients for cancer. Positive results are followed up by a more accurate and expensive test. It is assumed that the patient does not have cancer.
- Describe the null hypothesis, the Type I and Type II errors for this situation, and explain which type of error is more serious. The null hypothesis is that the patient does not have TB. Explain in words what it means that a screening test for TB has a power of 0. If you are conducting a hypothesis test of a single population mean, and you do not know the population variance, what test will you use if the sample size is 10 and the population is normal?
- If you are conducting a hypothesis test of a single population mean, and you know the population variance, what test will you use? If you are conducting a hypothesis test of a single population proportion, with np and nq greater than or equal to five, what test will you use, and with what parameters? Published information indicates that, on average, college students spend less than 20 hours studying per week. You draw a sample of 25 students from your college, and find the sample mean to be What distribution will you use to test whether study habits at your college are the same as the national average, and why?
- A published study says that 95 percent of American children are vaccinated against measles, with a standard deviation of 1. You draw a sample of children from your community and check their vaccination records, to see if the vaccination rate in your community is the same as the national average. What distribution will you use for this test, and why? If you get a result with a p-value of 0. You believe children with a particular disease are smaller than average, so you draw a sample of 20 children with this disease and find a mean height of What are the null and alternative hypotheses for this study? What distribution will you use to test your hypothesis, and why? What is the test statistic and the p-value? Based on your sample results, what is your decision? Suppose the mean for your sample was Redo the calculations and describe what your decision would be. What is the level of significance for this study? Nationally, 80 percent of adults own an automobile.
- You are interested in whether the same proportion in your community own cars. You draw a sample of and find that 75 percent own cars. What test will you use, and why? You conduct a poll of political opinions, interviewing both members of 50 married couples. Are the groups in this study independent or matched? You are testing a new drug to treat insomnia. You randomly assign 80 volunteer subjects to either the experimental new drug or control standard treatment conditions. You are investigating the effectiveness of a new math textbook for high school students. Use the following information to answer the next two exercises. You are conducting a study of the difference in time at two colleges for undergraduate degree completion. At College A, students take an average of 4. The pooled standard deviation for this data is 1. Suppose the mean time to earn an undergraduate degree at College A was 5.
- Calculate the effect size and interpret it. You conduct an independent-samples t-test with sample size ten in each of two groups. College students in the sciences often complain that they must spend more on textbooks each semester than students in the humanities. To test this, you draw random samples of 50 science and 50 humanities students from your college, and record how much each spent last semester on textbooks. Consider the science students to be group one, and the humanities students to be group two. What is the random variable for this study? Use an alpha level of 0. What is your conclusion? You want to know if proportion of homes with cable television service differs between Community A and Community B. To test this, you draw a random sample of for each and record whether they have cable service. What are the null and alternative hypotheses for this study If 65 households in Community A have cable service, and 78 households in community B, what is the pooled proportion?
- The content the exam tests has remained consistent, so, despite its age, this test is still a great resource to use and will give you a good idea of what your AP exam will be like. The exam has the same format as the current exam. Multiple-Choice Questions The College Board often reuses multiple-choice questions, so there are not many released official multiple-choice questions available for AP Stats. Besides the multiple-choice questions from the released exam, the only official multiple-choice questions you can use in your studying are in the AP Statistics Course Description. Beginning on page , there are 16 multiple-choice questions as well as 2 free-response questions , along with an answer key. Free-Response Questions Compared to multiple choice, there are many more official free-response questions you can use to study and, since they are recent, they'll give you a very accurate idea of what to expect on the real exam.

AP Statistics Exam Free-Response Question And Scoring Information Archive
AP Statistics practice test. It has 40 multiple-choice and 5 free-response questions. The questions are good; however, the links to the answer keys no longer work. For multiple-choice, click " score summaries " to see what the correct answers are. There's no way to see the free-response answers, but you already have a lot of official FRQ to use instead. It's rare for an unofficial source to have a full-length multiple-choice section, so even though you have to bounce around on the site a bit, we think it's worth it. Shmoop Shmoop is the only resource on this list that requires you to pay to access any of its resources. Stat Trek This is a complete, question, multiple-choice test. You can take the test timed or untimed, and you can choose to see the answer to each question immediately after you answer it or wait until the end of the exam to see what the correct answers were.- Some of these questions are a bit easier than those found on the real AP exam, but this is still a solid resource. Albert Albert organizes its practice questions into the four Big Ideas of AP Statistics, and the Big Ideas are further broken down into more specific topics, each with relevant short quizzes which can be useful if you're studying and want to easily find questions on certain subjects. The questions are ranked as easy, moderate, or difficult, they aren't timed, and you see the correct answer plus a detailed explanation after you answer each question.
- You will have to sign up for a free account, which includes a limited number of credits you can use to answer questions. Varsity Tutors The Varsity Tutors resources include four diagnostic tests and short practice quizzes, organized by topic. The four diagnostic tests each contain 40 multiple-choice questions and, like the Stat Trek test, they are similar to, but a bit easier than, the real AP exam.
- You're timed while taking the exams and, as a bonus, after you complete the exam, the questions are organized into different categories so you can see which categories you did best in and which categories you should focus your studying on. For this site, I'd recommend mostly using the diagnostic tests since most of the individual quizzes are so short only questions that it can be frustrating to continually start and finish separate quizzes. This is shorter than the multiple-choice section of the real AP exam, but this is a good resource to use if you want a shorter study session. The quiz is not timed and is automatically graded after you complete it. The questions are good quality, although you do have to grade the quiz yourself the correct letter is in bold in the answer key.

The free-response questions especially are shorter and easier than you'll find on the real AP exam, but you can still use this resource if you want to do some quick, targeted studying. How to Use These AP Statistics Practice Tests Knowing how to use each of these resources will make your studying more effective, as well as prepare you for what the real AP Statistics exam will be like.- Read the guide below to learn how and when you should use these practice tests and quizzes. First Semester Right now you're still learning a lot of key information, so during your first semester of AP Stats you should focus on quizzes and free-response questions on topics you've already covered. Begin using these materials about halfway through the semester. Multiple-Choice Practice For multiple-choice practice, take unofficial quizzes that let you choose which subjects you want to be tested on. This lets you review content you've already learned and avoid questions on material you haven't covered yet.
- The best resources for this are Albert, Varsity Tutors, and Dan Shuster because their quizzes are clearly organized by specific subject. Free-Response Practice For free-response questions, use the official released free-response questions from the Official Practice Exams section. There are a lot of questions available, so look through them to find questions you can answer based on what you've already learned. It's best if you answer a group of them up to six together at a time to get the most realistic preparation for the actual AP exam. It also helps to time yourself when answering these questions, particularly as it gets later in the semester. Try to spend about 12 minutes each on the first five questions and 30 minutes on the investigative task which will be the last question in the section.

Second Semester Second semester is when you can begin taking complete practice exams and continue reviewing content you've already learned. Follow these five steps: Step 1: Complete Your First Complete Practice Exam About a month or two into this semester, after you've covered a majority of the content you need to know for the AP exam, take your first complete practice exam. For this first practice test, I recommend using the official practice exam. You should take this test timed and in one sitting, then correct it when you're finished. If you haven't already, this is a good time to set a score goal for yourself. Aim for at least a 3 since this is the lowest passing score for the exam. However, if you scored a 3 or higher on this first practice exam, it's a good idea to set your goal score even higher, to a 4 or 5.
- Getting a higher score on the AP Stats exam looks more impressive to colleges, and it can sometimes get you more college credit. Step 2: Analyze Your Score Results After you've figured out your score, look over each problem you answered incorrectly and try to figure out why you got the question wrong. As you're doing this, look for patterns in your results. Are you finding that you got a lot of questions on experimental design wrong? Did you do well on multiple choice but struggled with free response? Figuring out which problems you got wrong and why is the best way to stop repeating your mistakes and make improvements for future exams.

Even if it seems tedious, don't be tempted to skip this step! Step 3: Focus on Your Weak Areas By now, you should have a good idea of the areas or techniques you need to work on to raise your score. If there are specific content areas you need to work on, review them by going over your notes, reading a review book, and answering multiple-choice and free-response questions that focus specifically on those topics. If you're struggling with your test-taking techniques, for example, running out of time on the exam or misreading questions, the best way to combat these issues is to answer a lot of practice questions under realistic testing conditions.- Step 4: Take Another Practice Exam After you've spent time improving your weak areas, it's time to see the results of your hard work. Take and score another complete practice exam, timed and finished in one sitting. Step 5: Review Your Results to Determine Your Future Study Plan Now you're able to see how much you've improved, and in which areas, since you took your first complete practice exam. If you've made improvements and have reached or are close to your target score, you may only need to do some light studying from now until the AP exam. However, if you haven't improved a lot, or you're still far from your score goal, you'll need to analyze the way you've been reviewing and think of ways to improve.
