Astudy was performed to determine whether men and women differ in their repeatability in assembling components on printed circuit boards. random samples of 25 men and 21 women were selected, and each subject assembled the units. what is the sampling distribution for the ratio of the sample variance s 2 men/s2 women? the two sample standard deviations of assembly time were swomen = 0.98 minutes and smen = 1.02 minutes. assume the assembling time for both men and women are normal random variables with variance 1. what is the probability that smen/swomen > smen/swomen (approximately 1.04)? based on the result, do you believe that we have enough evidence to say, women has less variance in assembling components?
