The operations manager of a musical instrument distributor feels that demand for a particular type of guitar may be related to the number of YouTube views for a music video by the popular rock group Marble Pumpkins during the preceding month. The manager has collected the data shown in the following table: YouTube views (1,000s) Guitar Sales 30 8 40 11 70 12 60 10 80 15 50 13 a. Using the equations presented in this chapter, compute the SST, SSE, and SSR. Find the least-squares regression line for these data (use manual computations) b. Using the regression equation, predict guitar sales if there were 40,000 views last month (use manual computations)
