Suppose that a random sample of 17 adult U.S. males hasa mean height of 70 inches with a standard deviation of 1.5 inches. If weassume that the heights of adult males in the U.S. arenormally distributed, find a 95% confidence interval for the mean height of all U.S. males.
Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
What are the lower and upper limits of the confidence interval?
