SST = SSR = The following data show the brand, price ($), and the overall score for six stereo headphones that were tested by Consumer Reports (Consumer Reports website). The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). The estimated regression equation for these data is ŷ = 23.2642 +0.3174x, where x = price ($) and y = overall score. Txy 82891778elSBN=9780357131596&id=1706455609&snapshotld=3320351& SSE b.
