Öne 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.

Use a 5% level of significance. a. State Ho and H1 b. Find the sample mean and sample standard deviation of the d values for the paired data.
