(a) The data given below represent the weights of 40 men and

60 women to the nearest pound. Of course we expect µ1 > µ2 .

Test µ1 = µ2 versus µ1 > µ2 using 2SAMP with a = 0.01.

{b) Estimate the difference µ1 - µ2 and find a 95% confidence

interval for this difference. How does your estimate

compare with the true difference of 10?
