The following data show the brand, price ($), and the overall score for six stereo headphones that were tested by Consumer Reports (Consumer Reports website). The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). The estimated regression equation for these data is O y = 22.5949 + 0.3241x , where x = price ($) and y = overall score.

Compute the coefficient of determination r2 (to 3 decimals). Comment on the goodness of fit. Hint: If r 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.
