Perform the indicated hypothesis test. Assume that the two samples are independent simple random samples selected from normally distributed populations.

1) A researcher was interested in comparing the amount of time spent watching television by women and by men. Independent simple random samples of 14 women and 17 men were selected, and each person was asked how many hours he or she had watched television during the previous week. The summary statistic are as follows.

Women: xbar1= 12.2hr s1= 4.4 hr n1= 14

Men: xbar2= 17.0 hr s2= 4.7 hr n2= 17

Use a 0.05 significance level to test the claim that the mean amount of time spent watching television by women is smaller than the mean amount of time spent watching television by men. Use the traditional method of hypothesis testing.
