10. A research group studying the use of Apple Pay asked the question, "Do you ever use Apple Pay payment at a grocery store?" to people selected from two random samples. One sample consisted of older adults, aged 35 years and older, and the other sample consisted of younger adults, ages 18 to 34 years old. The proportion of people who answered yes in each sample was used to create a 95 percent confidence interval of (0.097,0.125) to estimate the difference (younger minus older) between the population of people who would answer yes to the question. Which of the following is the best description of what is meant by 95 percent confidence? a) The probability is 0.95 that the difference in the population proportions of people who would answer yes to the question is between 0.097 and 0.125. b) The probability is 0.95 that the difference in the sample proportion of people who would answer yes to the question is between 0.97 and 0.125. c) In repeated random sampling with the same sample size, approximately 95% of the intervals tonstructed from the samples will capture the difference in population proportions of people who would answer yes to the question. make a n onnrovimately 95% of the intervals

A survey conducted by Gallup in 2020 asked 1,102 randomly selected U.S. adults, "What do you think is the ideal age for a woman to get married?" More than 50% of the adults selected the option, "Age 29 or younger". Based on these survey results, a researcher computed the 90% confidence interval for the proportion of U.S. adults who choose "Age 29 or younger" to be (0.6773, 0.7227). (a) What is the margin of error corresponding to this interval? (4 decimals)
A survey of credit card holders revealed that Americans carried an average credit card balance of $3900 in 1995 and $3300 in 1994 (U.S. News & World Report, January 1, 1996). Suppose that these averages are based on random samples of 400 credit card holders in 1995 and 450 credit card holders in 1994 and that the population standard deviations of the balances were $880 in 1995 and $810 in 1994. Construct a 95% confidence interval for the difference between the mean credit card balances for all credit card holders in 1995 and 1994. a. ($285.81, $414.19) b. ($435.81, $700.19) c. ($845.81, $9984.19) d. ($485.81, $714.19)

15. Pain after surgery: In a random sample of 50 patients undergoing a standard surgical procedure, 15 required medication for postoperative pain. In a random sample of 90 patients undergoing a new procedure, only 16 required pain medication. a. Construct a 95% confidence interval for the difference in the proportions of patients needing pain medication between the old and new procedures. b. A physician claims that the proportion of patients who need pain medication is the same for both procedures. Does the confidence interval contradict this claim? 16
A study of 420 comma 026 cell phone users found that 140 of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0434 % for those not using cell phones. Complete parts (a) and (b). a. Use the sample data to construct a 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system. b. Do cell phone users appear to have a rate of cancer of the brain or nervous system that is different from the rate of such cancer among those not using cell phones? Why or why not?
