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. Give 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: X ? Upper limit: Save For Later Submit Assignment
