Suppose that textbook weights are normally distributed. You measure 50 textbooks' weights, and find they have a mean weight of 77 ounces. Assume the population standard deviation is 13.7 ounces. Based on this, construct a 99% confidence interval for the true population mean textbook weight. Round answers to 2 decimal places. Select an answer
