{Exercise 12.18 (Algorithmic)} The following data show the brand, price ($), and the overall
score for 6 stereo headphones that were tested by Consumer Reports.
The overall score is based on sound quality and effectiveness of
ambient noise reduction. Scores range from 0 (lowest) to 100
(highest). The estimated regression equation for these data is ŷ =
25.989 + 0.29x, where x = price ($) and y = overall
score.
Round your answers to three decimal places. a. Compute SST, SSR, and SSE.
b. Compute the coefficient of determination r2. Comment on the goodness of fit. r2 = c. What is the value of the sample correlation coefficient? r = |
