Net Sales ($ billion) 50 60 70 80 Operating Expenses ($ billion) 11 16 23 25 a. Use this information to find a linear regression model for Amazon's operating expenses E (in billions of dol- lars) as a function of net sales S (in billions of dollars). Plot the data and regression line. b. Give the units of measurement and interpretation of the slope. c. What, according to the model, would Amazon need to earn in net sales for its operating expenses to be $5 bil- lion? (Round answer to the nearest billion dollars.) d. Based on the graph, would you say that the linear model is reasonable? Why or why not? 27.
