Please help answer the following questions. Provide your answers in Excel.

14. In a 2-tail hypothesis test on a population mean, what is the p-value or OSL of the hypothesis test if the calculated test statistic based on 11 observations is 3.169 and the pop. variance is unknown?

15. How large of a sample would be required to estimate the average cost of a medium-sized house to within $2000 with a 99% confidence interval if the range of house prices is $39,000?
