Suppose that the average amount paid by customers at a grocery store is $80. The standard deviation of the amounts paid is $24. The distribution of the amounts paid is skewed. (Notice that the individuals here are customers and the variable is the amount paid per customer.) Consider randomly selecting 40 customers and calculating the average amount paid per customer in the sample. Do this many times. What percentage of all the sample averages would exceed $75? (That is, what is the chance that the average of 40 randomly selected amounts paid exceeds $75?) Please show all the steps as well as an appropriate diagram
