Twenty-five students were randomly selected from each of three colleges in a particular region and were asked to report on the amount of time they spent socializing each day with other students. The results for college x was a mean of 5 hours and an estimated population variance of 2 hours: for college y, m= 4, s2=1.5; and for college Z, M= 6, s2 =2.5 what should you conclude?
