Published data indicates that in 2008 mid-level management travelers spent an average of $381 per day with a standard deviation of $47 when they were in Chicago on business. The accounting firm Ernst and Sachs randomly selected a sample of 65 of their accountants who had traveled to Chicago in 2008. Please compute the probability of getting a sample average of more than $373 per day if Ernst and Sachs accountants are generally similar to the national population for which the published data (mentioned in the first sentence) is available.
