Random samples of 25 men 21 women were selected, and each subject assembled the units. The two sample standard deviations of assembly time were 0.98 minutes for men 1.02 minutes for women. Is there evidence to support the claim that men and women differ in repeatability for this assembly task at 0.08 level of significance? Use Excel to do all the computations. Answer all the questions below and upload your Excel file to the last question and submit.
