Suppose that a random sample of 15  adult U.S. males has a mean height of 70  inches with a standard deviation of 2.9 inches. If we assume that the heights of adult males in the U.S. are normally distributed, find a 99 % confidence interval for the mean height of all U.S. males. Then complete the table below. 

Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)
