2. A study reported in The Journal of Consumer Research dealt with the influence of touch on customer's evaluation of service. Experimenters were trained as servers in a restaurant. In alternating hours, the servers either touched or not touch the diners. The mean and standard deviation ratings given by a random sample of 35 female diners who were touched were 3.84 and 1.15 respectively, and a random sample of 38 female diners who were not touched gave mean and standard deviation ratings of 2.25 and 0.92 respectively. Test the hypothesis at the 0.05 level of significance that the population mean rating given by diners who are touch is less than the population men rating by those who are not touched.
