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 60 dates, the mean record high daily temperature in a certain city has a mean of 85.14°F. Assume the population standard deviation is 14.96°F.
