We are 95% confident that the boundaries for the interval are $ enter your response here and $ enter your response here. C. We are 95% confident that the sample mean is between $ enter your response here and $ enter your response here. Part 2 b. Can we reject a population mean of $19 comma 580 on the basis of these numbers? Explain. A. No, do not reject $19 comma 580. Since $19 comma 580 is not in the interval, it is plausible the population mean student debt is $19 comma 580. B. Yes, reject $19 comma 580.
