Question: Are America’s top chief executive officers (CEO) really worth all that money? One way to answer this question is to look at the percentage of increase in company revenue versus CEO’s annual percentage salary increase in that company. [Forbes Vol. 159, No 10].

Percent for company 24 23 25 18 6 4 21 37

Percent for CEO 21 25 20 14 -4 19 15 30

Do these data indicate that the population means percentage increase in corporate revenue is different from the population mean percentage increase in CEO salary? Use a 5% level of significance.
