The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). The estimated regression equation for these data is y = 25.8000 + 0.2920z , where = = price ($) and y = overall score. Brand Price ($) Score Bose 180 76 Scullcandy 160 72 Koss 95 61 Phillips/O'Neill 60 57 Denon 60 30 JVC 45 34 a. Compute SST, SSR, and SSE (to 3 decimals) SST - SSR SSE - X b. Compute the coefficient of determination ? (to 3 decimals). P = Comment on the goodness of fit. Hint: If ra is greater than 0.70, the estimated regression equation provides a good fit. The least squares line provided a good fit as a large proportion of the variability in y has been explained by the least squares line. C. What is the value of the sample correlation coefficient (to 3 decimals)? Hide Feedback Partially Correct
