The annual cost of diapers for families that have one or more children under the age of 4 is skewed to the right with a mean of $1,225 and a standard deviation of $633. If a random sample of 15 families that have one or more children under the age of 4 are selected, what is the probability that their mean annual diaper cost is more than $1,500? Is it appropriate to calculate this probability? If yes, use this standard Normal table to calculate the probability and select the correct probability. If no, then select "Not appropriate."
