A bookstore at a large college claims that the mean amount of moneyeach student spends on books each semester is $252.92 with a standard deviation of $58.21. On the study trip an SRS of 40 current students says they have spent an average of $265.16 on books. What is the probability that a sample of this size will have an average amount spent that is between $260 and $270?
