Question

Sally is interested in finding out if the political party affiliation of Americans who are registered to vote is related to whether or not they believe in ghosts. Suppose she finds that, among all Americans who are registered to vote, 29.529.5% are registered Democrats and 24.624.6% are registered Republicans. Among all registered American voters, the percent of people who are Democrat and who believe in ghosts is 7.87.8%, the percent of people who are Republicans and who believe in ghosts is 6.56.5%, and the percent of people who affiliate with other political parties and who believe in ghosts is 12.112.1%.

A researcher wanted to study the tendency of people’s choices to be influenced by their environment, so she conducted an experiment. The researcher recruited 90 volunteers. She randomly assigned 30 to sit in a room with red walls, 30 to sit in a room with yellow walls, and 30 to sit in a room with orange walls. After sitting in the room for a while doing mundane activities, she offered them all a snack of strawberries, bananas, or oranges. For each individual, she recorded which room the participant was in and which snack they chose. The data are displayed in the table. The researcher would like to know if these data provide convincing evidence that the distribution of snack choice differs for the various room colors in the population of all volunteers like these. Are the conditions for inference met?
An anger-management course claims that, after completing its seminar, participants will lose their tempers less often. Aways a skeptic you decide to test this claim. A random sample of 12 seminar participants is chosen, and these participants are asked to record the number of times that they lost their tempers in the two weeks prior to the course. After the course is over, the same participants are asked to record the number of times that they lost their tempers in the next two weeks. The following table lists the results of the survey. Using these data, test the claim at the 0.02 level of significance assuming that the population distribution of the paired differences is approximately normal.

To test a drug intended to increase memory, 80 subjects were randomly given a pill that either contained the drug or was a placebo. After ten minutes, the subjects were asked to look at a poster with pictures of 20 common objects for five minutes. After waiting ten minutes, the subjects were asked to list as many of the objects as they could recall. For the subjects that took the drug, 75% were able to list at least half of the objects. For the subjects that took the placebo, 70% were able to list at least half of the objects. Check that the conditions are met for a hypothesis test to compare the population proportion of subjects that took the drug that could list at least half of the objects to the proportion that took the placebo that could. Select the correct answer below: All of the conditions are met. The samples are not random samples of the populations. O The samples are not independent. Not all the values np. n₁q. nap, and nag are at least 5.
