Question: ATM Withdrawals – The manufacturer of a certain type of ATM machine reports that the mean ATM withdrawal is $60. The manager of a convenience store with an ATM machine claims that mean withdrawal from his machine is less than this amount. He obtains a random sample of 35 withdrawals over the past year and finds the sample mean to be $52. Assume that the population standard deviation is $13. Test the manager’s claim using either the classical approach or the P-value approach at the a = 0.05 level of significance.
