Question

drinking with AA (Alcoholics Anonymous), and we find that 39 of them were able to stay clean after their 2 -month check in. Can we construct a 95% confidence interval for the proportion of alcoholics who are able to stay clean after their 2 -month check in? Check the assumptions. Yes. This is a SRS, and n>30. No. This is a SRS, but there are not at least 10 individuals in each category. Yes. This is a SRS, and there are at least 10 individuals in each category. Question 3 (1 point) Suppose we survey CMU students and find that out of 130 randomly selected CMU students, 47 of them have never been to the CMU Hamilton Recreation Center. Run a 90% confidence interval and give the correct interpretation. We are 90% confident that 29-43% of these 130 CMU students have never been to the CMU Hamilton Recreation Center. We are 90% confident that 29-43% of all CMU students have never been to the CMU Hamilton Recreation Center. We are 90% confident that the proportion of CMU students from this sample who have never been to the CMU Hamilton Recreation Center is between 29% and 43%. Question 4 (1 point) CMU reports that, for the 20-21 academic year, the average high school GPA for all? freshmen is 3.23 . Suppose we take a random sample of 53 freshmen who are majoring in criminal justice and find their mean high school GPA is 3.29 with a standard deviation of 0.31 . Does the high school GPA for freshmen criminal justice majors differ from the overall high school GPA of CMU freshmen? Give the p-value and report the correct conclusion. Use alpha =0.05. p=0.1314. There is not enough evidence that criminal justice freshmen have a different mean GPA than the general population of CMU freshmen. p=0,1314. There is enough evidence that criminal justice freshmen have a different mean GPA than the general population of CMU freshmen. p=0,1648.
