Suppose that the student body in a large university have normally distributed GPAs with a mean of μ=2.91 and standard deviation σ=0.38. You randomly select a sample of n=29 students. The probability is 0.95 (with the complement split evenly between the tails) that the standard deviation of your sample will be between what two numbers?
