1. The operations manager of Yamaha Philippines, a musicalinstrument distributor, feels that demand for Yamaha guitarmay be related to the number of YouTube views for a musicvideo by the popular rock group Eraserheads which uses theguitar in its shows during the preceding month. The managerhas collected the data shown in the following table:YouTube Views (1,000s) Guitar Sales40507060805090100801208111210151316151418a. Graph these data to see whether a linear equation mightdescribe the relationship between the views on YouTube andguitar sales.b. Using the regression equation, interpret the Y intercept andthe slope.c. Predict guitar sales if there were 100,000 views last month.d. Determine and interpret the coefficient of determination andthe coefficient of correlation.e. Test to see if there is a statistically significant relationshipbetween YouTube views and guitar sales at the 0.05 level ofsignificance.
