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 75 dates, the mean record high daily temperature in a certain city has a mean of 82.23°F. Assume the population standard deviation is 14.04°F. ... The 90% confidence interval is ( .). (Round to two decimal places as needed.)
