O Thirty-two percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). Suppose you have been hired by the Natural Resources Defence Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the College Success Tips proportion who drink bottled water more than once a week. Assume the population proportion of St. Paulites who drink bottled water more than once a week is 0.32, the same as the overall proportion of Americans who drink bottled water more than once a week. Use z-table. Career Success Tips a. Suppose you select a sample of 540 St. Paulites. Show the sampling distribution of p (to 4 decimals). RECOMMENDED FOR YOU E(P) = .32 Op = 0.0269 x b. Based upon a sample of 540 St. Paulites, what is the probability that the sample proportion will be within 0.03 of the population proportion (to 4 decimals). probability = bongo Preparing a Successful c. Suppose you select a sample of 150 St. Paulites. Show the sampling distribution of p (to 4 decimals). Presentation E(P) = .32 Op = 0.0269x ? Help d. Based upon a smaller sample of only 150 St. Paulites, what is the probability that the sample proportion will be within 0.03 of the population proportion (to 4 decimals) Give Feedback probability = A+ e. As measured by the increase in probability, how much do you gain in precision by taking the larger sample in parts (a) and (b) rather than the smaller sample in parts (c) and (d)? - Select your answer - vx X - Select your answer - V X Hide FeedbackX X X + Assignments: MC 2022 FALL-C X MindTap - Cengage Learning X MindTap - Cengage Learning Ztable.png (680x898) Course Hero Update : C https://cnow.apps.ng.cengage.com/ilrn/books/asmb06h/images/tables/Ztable.png TABLE 1 CUMULATIVE PROBABILITIES FOR THE STANDARD NORMAL RIBUTION (Continued) Cumulative Entries in the table probability give the area under the curve to the left of the z value.
