Question: The financial information in the Excel file associated with this exercise was obtained from Form 10-K reports for Costco Wholesale Corporation. In this exercise, we examine how changing the starting point (baseline) of the y-axis from 0.0, impacts the chart that is created. The chart that is created for Costco examines return on equity over a five-year period. The return on equity ratio (Net income/Average stockholders' equity) measures the return of the stockholders' investment in the company. An increase in the ratio generally means that the company is more efficiently using its equity to generate profits.
