Suppose that a random sample of 16 adult U.S. males has a mean height of 69 inches with a standard deviation of 1.5 inches. If we assume that the heights of adult males in the U.S. are normally distributed, find a 90% confidence interval for the mean height of all U.S. males. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit:| Upper limit:

Suppose that a random sample of 16 adult U.S. males has a mean height of 69 inches with a standard deviation of 1.5 inches. If we assume that the heights of
adult males in the U.S. are normally distributed, find a 90% confidence interval for the mean height of all U.S. males. Then find the lower limit and upper limit
of the 90% confidence interval.
Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)
