For the following test, assume that the two samples are independent simple random samples selected from normally distributed populations and that the population standard deviations are equal (01 = 02) so that the standard error of the difference between means is obtained by pooling the sample variances. A researcher was interested in comparing the amount of time spent studying baboons by women and men from a group of anthropologists. Independent simple random samples of 35 women and 36 men were selected, and each person was asked how many hours they had studied the baboons during the previous week. The summary is shown in the table. Women Men n - 35 women = 36 men n2 I, = 17.1 hours , - 17.2 hours 52 = 2.3 hours %3D 51 = 1.5 hours Use a 0.1 significance level to test the claim that the mean amount of time spent studying baboons by women is smaller than it is for men.
