Question

You investigate 14 randomly selected McD's small fry orders, and find that on average (mean), they contain 131 fries. Assume the population standard deviation is 14.2 fries. Based on this, construct a 99% confidence interval for the true population mean number of french fries in a small order. Assume the distribution of french fries in small orders is normal. Give your answers as decimals, to two places < \mu <
