1. 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:

You tube VIEWS (1,0000	GUITAR SALES
30
40	11
70	12
60	10
80	15
50	13

(a) Graph these data to see whether a linear equation 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.

2. Using the data in Problem 3-10, test to see if there is a statistically significant relationship between sales and YouTube views at the 0.05 level of significance.

Use the formulas in this chapter and Appendix D
