A study was performed to determine whether men and women differ in repeatability in assembling components on printed circuit boards. Random samples of 25 men and 21 women were selected, and each subject assembled the units. The two sample standard deviations of assembly time were s men = 0.98 minutes and s women = 1.02 minutes. (a) Is there evidence to support the claim that men and women differ in repeatability for this assembly task? Use α = 0.02 and state any necessary assumptions about the underlying distribution of the data.
