To determine the views of students on a particular campus about fraternities, an 11-point attitude scale was administered to a random sample of 25 students. This survey yielded a sample mean of 5 (the higher the score, the more favorable the view of the fraternities) and a standard deviation of 1.5. Find the 95% confidence interval for the population mean.
