A researcher was interested in comparing the amount of time (in hours) 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 statistics are as follows. Women x1=12.5 hr women is smaller than the mean amount of time spent watching television by men. Use the traditional method of hypothesis testing. 9) A large software company gives job applicants a test of programming ability and the mean for that test has been 160 in the past. Twenty-five job applicants are randomly selected from one large university and they produce a mean score and standard deviation of 183 and 12, respectively. Use a 0.05 level of significance to test the claim that this sample comes from a population with a mean score greater than 160. Use the P -value method of testing hypotheses. Men x2=13.8 hr s2 = 5.2 hr n2 = 17Use a 0.05 significance level to test the claim that the mean amount of time spent watching television by s1 = 3.9 hr n1 = 14
