A sample of 100 students was taken from the introductory statistics classes. This group averaged 74.5 on the final exam with sample standard deviation of 3.2. Assuming that this group is a random sample of all students who have taken statistics and scores in the final exam for all students are approxiamately normally distributed, what is the approxiamate 95% cinfidence interval for the true population mean of all statistics students?
