Refer to the Wendy’s Widgets data in M5-7. Suppose Wendy performed a least-squares regression and obtained the following results.

Put Wendy’s results into a linear equation format (Y = A + BX) and explain what each component means. Compare the regression results to those obtained in M5-7 and M5-8. Which method is most accurate? Why?

Data from M5-8

Refer to the Wendy’s Widgets data in M5-7. Using the high-low method, calculate the total fixed cost per month and the variable cost per widget. How does the estimate of fixed cost compare to what you estimated in M5-7?

Data from M5-7

Wendy’s Widgets builds the world’s best widgets. Information for the last eight months follows:

Prepare a scattergraph by plotting Wendy’s data on a graph. Then draw a line that you believe best fits the data points. Using the graph and line you have drawn, estimate Wendy’s total fixed cost per month.
