Do students at various colleges differ in how sociable they are? 25 students were randomly selected from each of 3 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 were a mean of 5 hrs and population variance of 2 hrs. For College Y, M=4, s2=1.5, and College Z M=6, s2=2.5. What should you conclude? Use the .05 level. Figure the effect size for the study.
