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 83 33 F. Assume the population standard deviation is 13 98 F The 90% confidence interval is (Round to two decimal places as needed )
