Suppose you use simple random sampling to select and measure 37 backpacks' weights, and find they have a mean weight of 73 ounces. Assume the population standard deviation is 11.4 ounces. Based on this, construct a 99% confidence interval for the true population mean backpack weight. Give your answers as decimals, to two places ± ounces
