Suppose that a random sample of 13 adult U.S. males has a mean heightof 71 inches with a standard deviation of 1.5 inches. If we assume that theheights 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 thelower 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.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
