You 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 71 ​dates, the mean record high daily temperature in a certain city has a mean of 85.80 degrees°F. Assume the population standard deviation is 14.03 degrees°F.

The​ 90% confidence interval is ​(?​,?​). ​(Round to two decimal places as​ needed.)
