A factory hiring people for tasks on its assembly line givesapplicants a test of manual dexterity. This test counts how manyoddly shaped parts the applicant can install on a model engine ina​ one-minute period. Assume that these tested applicantsrepresent simple random samples of men and women who apply forthese jobs.
Find the​ 95% confidence interval for the difference μmen−μ women.

A factory hiring people for tasks on its assembly line gives applicants a test of manual dexterity. This test counts how many oddly shaped part 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. Normality describes the sampling distribution of the average and not the individual. OB. The normal model cannot be used in this situation. OC. The normal model can be used because the sample size is less than 30.. (c) Your intervals in part a should overlap. What does it mean that the intervals overlap? C Get Hom Question 7, 17.1.30-T Part 4 of 6 C (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 21.81,26.19 The 95% confidence interval for the expected number of parts that women can install is (24.98, 32.19 (Round to two decimal places as needed.) (b) These data are counts, and hence cannot be negative or fractions. How can we use the normal model in this situation?
