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)
