3. A study is conducted to compare the length of time between men and women to assemble a certain product. Experience shows that the distribution of times for both men and womnen is normal, but the variance of the times for women is less than for men. A random sample of N1 = 14 of the times for men has a standard deviation S1 %3D = 7.2, and a random sample of N2 = 16 of the times for women has a %3D standard deviation S2= 5.8.
