Constructing Confidence Intervals In Exercises 35–38, you are given the sample mean and the population standard deviation. Use this information to construct 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. 37. Maximum Daily Temperature From a random sample of 64 dates, the mean record high daily temperature in the Chicago, Illinois, area has a mean of 84.13°F. Assume the population standard deviation is 14.56°F. (Source: NOAA)
