Transcribed Image Text:Check My Work (4 remaining) 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 guality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). The estimated regression equation fothese data is ý27.8615 + 0.2714, where z- price (8) and y- orerall score.
