Psychologists at an university compared the levels of alcohol consumption of male and female freshman students. Each student was asked to estimate the amount of alcohol (beer, wine, or liquor) they consume in a typical week Summary statistics for 129 males and 184 females are provided in the accompanying table. Click here to view the table For each gender, find a 95% confidence interval for mean weekly alcohol consumption Formales, the 95% confidence interval is (Round to the nearest hundredth as needed) Let to be a specific value of t. Use the table of critical values of t below to find to-values such that following statements are true. a. P (tzto) = .025, where df = 11 b. P(tzto) = .01, where df = 18 c. P (tst) = .005, where df = 6 d. P(tsto) = .05, where df = 13 Click the icon to view the table of critical values of t. a. The value of to is The random sample shown below was selected from a normal distribution. 7, 8, 9, 4, 6, 2 Complete parts a and b. a. Construct a 99% confidence interval for the population mean ?. (Round to two decimal places as needed.)
