A factory hiring people for tasks on its assembly line gives applicants a test of manual dexterity. This test counts how many oddly shaped parts the applicant can install on a model engine in a one-minute period. Assume that these tested applicants represent simple random samples of men and women who apply for these jobs. Complete parts (a) through (f). Click the icon to view the table of gender and number of parts installed. (a) Find the 95% confidence interval for the expected number of parts that men and women can install during a one-minute period. The 95% confidence interval for the expected number of parts that men can install is (21.89 26.10) The 95% confidence interval for the expected number of parts that women can install is (25.3.32.22) (Round to two decimal places as needed.)
