Question

Sallie Mae researchers report that the average college junior has a credit card debt of $2912. Under the assumption that this finding was based on the sample data in file XR09040, construct and interpret the 99% confidence interval for the population mean credit card debt for college juniors. Based on this confidence interval, would it seem very unusual if another sample of this size were to result in a mean of $3150?
