4-10 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 follow- ing table: YouTube VIEWS (1,000s) 30 40 70 60 80 50 GUITAR SALES 8 11 12 2953 10 15 13 (a) Graph these data to see whether a linear equa- tion might describe the relationship between the views on YouTube and guitar sales. (b) Using the equations presented in this chapter, compute the SST, SSE, and SSR. Find the least- squares regression line for these data. (c) Using the regression equation, predict guitar sales if there were 40,000 views last month. 4-12 Using computer software, find the least-squares re- gression line for the data in Problem 4-10. Based on the F test, is there a statistically significant relation- ship between the demand for guitars and the number of YouTube views?
