One of the variables is the customer's age. For the 25 customers, the ages and a histogram of those ages are shown to the right. Complete parts a) through c). 30 30 15 29 11 37 22 43 47 25 25 22 31 36 32 36 42 43 43 48 0 # of Customers 25 Age a) Would you expect the mean age to be smaller than, bigger than, or about the same size as the median? Explain. OA. The mean age should be bigger than the median because the distribution is skewed to the right. XB. The mean age should be smaller than the median because the distribution is skewed to the left. c. The mean age should be about the same size as the median because the distribution is roughly symmetric. b) Find the mean age. The mean is 50 The marketing team at an internet music site wants a better understanding of who their customers are.
