Consumer Reportsprovided 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 data show the price and overall score for the ten 42-inch plasma televisions (Consumer Reportdata slightly changed here):

Brand Price Score

Dell 3500 60

Hisense 2800 55

Hitachi 3200 45

JVC 3500 50

LG 3300 55

Maxent 2000 30

Panasonic 4000 70

Phillips 3000 55

Proview 2500 35

Samsung 3000 40

Use the above data to develop an estimated regression equation and interpret results. Compute the Coefficient of Determination and the correlation coefficient and show their relation.
