Astudy was performed to determine whether men and women differ in their repeata-bility in assembling components on printed circuit boards. random samples of 25men and 21 women were selected, and each subject assembled the units. what is thesampling distribution for the ratio of the sample variances2men/s2women? the two sam-ple standard deviations of assembly time wereswomen= 0.98 minutes andsmen= 1.02minutes. assume the assembling time for both men and women are normal randomvariables with variance 1. what is the probability thatsmen/swomen> smen/swomen(approximately 1.04)? based on the result, do you believe that we have enoughevidence to say, women has less variance in assembling components?
