Q2. Are America's top chief executive officers (CEOs) really worth all that money? One way to answer this question is to look at row B, the annual company percentage increase in revenue, versus row A, the CEO's annual percentage

salary increase in that same company. Do these data indicate that the population mean percentage increase in corporate revenue (column A) is different from the population mean percentage increase in CEO salary? Use a 5% level of significance. a. Formulate the null and alternate hypothesis.
