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. Suppose that a random sample of companies yielded the following data: B: Percent for company 13 30 30 5 18 8 19 4 A: Percent for CEO 12 23 28 7 21 7 12 6   Do these data indicate that the population means a percentage increase in corporate revenue (row B) is different from the population mean percentage increase in CEO salary? Use a 10% level of significance. What is α? Group of answer choices 0.800 0.900 0.050 0.950 0.100
