Suppose that textbook weights are normally distributed.
You measure 26 textbooks' weights, and find they have a mean weight
of 69 ounces. Assume the population standard deviation is 8.8
ounces. Based on this, construct a 99% confidence interval for the
true population mean textbook weight. Round answers to 2 decimal
places.
