Consumer Reports provided extensive testing and ratings for more than 100 HDTVs. An overall score, based primarily on picture quality, was developed for each model. In general, a higher overall score indicates better performance. The following (hypothetical) data show the price and overall score for the ten 42-inch plasma televisions (Consumer Report data slightly changed here):

Brand                      Price             Score

Dell                         2800             60

Hisense                  2800             55

Hitachi                    2700             45

JVC                        3500             50

LG                          3300             55

Maxent                   2000             38

Pansonic                4000             67

Phillips                    3000            56

Proview                  2500            32

Samsung                3000            40

 

Use the above data to develop and estimated regression equation. Compute Coefficient of Determination and correlation coefficient and show their relation. Interpret the explanatory power of the model. Estimate the overall score for a 42-inch plasma television with a price of $3800.
