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 49   business​ days, the mean closing price of a certain stock was ​$109.89 . Assume the population standard deviation is ​$10.27 .
