Question description
Â
How much credit card debt do students typically have when they graduate from a university? A sample of 15 recent George Washington University graduates is obtained. Each of these recent graduates is asked to indicate the amount of credit card debt they had at the time of graduation. It turns out that the sample mean was $2430 with a sample standard deviation of $2300. Would it be appropriate to use the method above to find a 99% confidence interval for the average credit card debt for all recent George Washington University graduates?
