How much credit card debt do students typically have when they graduate from Penn State? Suppose a sample of 20 recent Penn State graduates was obtained. Each of these recent graduates was asked to indicate the amount of credit card debt they had at the time of graduation. This is a summary of the information that was obtained from this sample: sample mean = $2430, sample standard deviation = $2300. Find a 96% confidence interval estimate for the mean card debt of all Penn State graduates. Give complete confidence statement. Round only the last calculation (both endpoints) to two decimal places.
