Jeff Friedman was a section chief for an electric utility company. After the numbers in one of his reports to the management of the utility didn't add up, he was reassigned to the home economics department. He interviewed 131 people in a suburban shopping center to discover some of their cooking habits. He obtained the results shown to the right. 52 use microwave ovens; 69 use electric ranges; 52 use gas ranges; 19 use microwave ovens and electric ranges; 21 use microwave ovens and gas ranges; 3 use both gas and electric ranges; 1 uses all three; 2 uses none of the three. Should he be reassigned one more time? Why or why not?
