Hint: For the calculations, assume the women as the first sample.
a.State the decision rule for 0.02 significance level:H0: f m;H1: f> m.(Round the final answer to 3 decimal places.)
RejectH0ift>=
b.Compute the pooled estimate of the population variance.(Round the final answer to 3 decimal places.)
Pooled estimate of the population variance=
c.Compute the value of the test statistic.(Round the final answer to 3 decimal places.)
Value of the test statistic=
