3. A study was performed to determine whether men and women differ in repeatability in assembling components on a specific engine part. Random samples of 28 men and 25 women were selected, and each subject assembled the units. The two sample standard deviations of assembly 2.31 minutes. Do we accept time were Smen = 1. 98 minutes and Swomen the claim that men and women differ in repeatability for this assembly task? Use a = 0.02. (Treat Smen as s1, and Swomen as s2)
