Question

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 time were S??? = 1.98 minutes and S????? = 2.31 minutes. Do we accept the claim that men and women differ in repeatability for this assembly task?

Use α = 0.02. (Treat S??? ?? S1,??? S????? ?? S2)
