Develop the estimated regression equation that can be used to predict the Overall Rating using the Contrast Ratio Rating (to 4 decimals if necessary). The regression equation is: Overall Rating = + Contrast Ratio b. Develop the estimated regression equation that can be used to predict the Overall Rating using both the Contrast Ratio Rating and the Resolution Rating (to 4 decimals if necessary). The regression equation is: Overall Rating = + Contrast Ratio + Resolution c. Predict the overall Overall Rating for a computer monitor computer that has a Contrast Ratio Rating of 85 and a Resolution Rating of 74 (to the nearest whole number).
