VYou are given the sample mean and the population standard deviation. Use this information to construct the​ 90% and​ 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of  59 ​dates, the mean record high daily temperature in a certain city has a mean of 82.74 F. Assume the population standard deviation is14.56 F.
