The cost of textbooks is normally distributed with a mean of $239. You do not know the population standard deviation, but you estimate the sample standard deviation to be $47. What is the probability that from a sample of 7 textbooks, their average cost will be between $204 and $270? (Report answer accurate to three decimal places.)
