Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 74 people in the 18-21 age bracket and finds that 63 of them respond and 11 refuse to respond. When 278 people in the 22-29 age bracket are contacted, 260 respond and 18 refuse to respond. Assume that 1 of the 352 people is randomly selected. Find the probability of getting someone in the 18-21 age bracket or someone who responds. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(18-21 or responds) = (Hint: It might be helpful to organize the data into a table first.)

Suppose you want to find out how many people support Policy X. A standard polling approach is to just ask N many people whether or not they support Policy X, and take the fraction of people who say yes as an estimate of the probability that any one person supports the policy. Suppose that the probability someone supports the policy is p, which you do not know. Let pn be the number of people polled who supported the policy, divided by the total number of people polled N.

Based on a smartphone survey, assume that 51% of adults with smartphones use them in theaters. In a separate survey of 248 adults with smartphones, it is found that 110 use them in theaters. a. If the 51% rate is correct, find the probability of getting 110 or fewer smartphone owners who use them in theaters. b. Is the result of 110 significantly low? a. If the 51% rate is correct, the probability of getting 110 or fewer smartphone owners who use them in theaters is (Round to four decimal places as needed.) b. Is the result of 110 significantly low? v because the probability of this event is v than the probability cutoff that corresponds to a significant event, which is Question Viewer Enter your answer in the answer box. ?
