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 48 business days, the mean closing price of a certain stock was $114.60. Assume the population standard deviation is $11.01.
