MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A college student organization wants to start a nightclub for students under the age of 21. To assess support for this proposal, they will select an SRS of students and ask each respondent if he or she would patronize this type of establishment. They expect that about 74% of the student body would respond favorably. (a) What sample size is required to obtain a 80% confidence interval with an approximate margin of error of 0.03? (b) Suppose that 54% of the sample responds favorably. Calculate the margin of error for the 80% confidence interval. 9. [-/1 Points] DETAILS YMSSTAT2 12.E.012. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER PTC is a substance that has a strong bitter taste for some people and is tasteless for others. The ability to taste PTC is inherited. About 65% of Italians can taste PTC, for example. You want to estimate the proportion of Americans with at least one Italian grandparent who can taste PTC. Starting with the 65% estimate for Italians, how large a sample must you test in order to estimate the proportion of PTC tasters within + 0.048 with 95% confidence? 10.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER An experiment on the side effects of pain relievers assigned arthritis patients to one of several over-the-counter pain medications. Of the 461 patients who took one brand of pain reliever, 19 suffered some "adverse symptom," Does the experiment provide strong evidence that fewer than 9% of patients who take this medication have adverse symptoms? (Use a = .05.) P-value = Conclusion There is significant evidence that fewer than 9% of patients who take this medication have adverse symptoms. There is no evidence that fewer than 9% of patients who take this medication have adverse symptoms
