The following data show the brand, price ($), and the overall score for six stereo headphones that were tested by Consumer Reports (Consumer Reports website). The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). The estimated regression equation for these data is y = 24.7708 + 0.3023x , where x = price ($) and y = overall score.

Compute the coefficient of determination " (to 3 decimals). 12 = Comment on the goodness of fit. Hint: If y is greater than 0.70, the estimated regression equation provides a good fit. The least squares line - Select your answer - | a good fit as |- Select your answer - v| 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)? Try = 0- Icon KeyDuring the first 13 weeks of the television season, the Saturday evening 8:00 PM. to 9:00 P.M. audience proportions were recorded as ABC 30%, CBS 27%, NBC 25%, and Independents 18%. A sample of 300 homes two weeks after a Saturday night schedule revision yielded the following viewing audience data: ABC 93 homes, CBS 62 homes, NBC 83 homes, and Independents 62 homes. Test with o = 0.05 to determine whether the viewing audience proportions changed. Find the test statistic and p-value. (Round your test statistic to two decimal places. Use Table 3 of Appendix B.) Test statistic = p-value is - Select your answer - Conclusion: There is - Select your answer - V change in the viewing audience proportions. O- Icon Key
