[paisley14]

You measure 20 randomly selected textbooks' weights, and find they have a mean weight of 58 ounces. Assume the population standard deviation is 10.9 ounces. Based on this, construct a 90% confidence interval for the true population mean textbook weight.

Give your answers as decimals, to two places
