(Round your numerical values to two decimal places. Let x, represent the contrast ratio rating and y represent the overall rating.) (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. (Round your numerical values to two decimal places. Let x, represent the contrast ratio rating, x, represent the resolution rating, and y represent the overall rating.) (c) Predict the overall rating for a computer monitor computer that has a contrast ratio rating of 85 and a resolution rating of 74. (Round your answer to the nearest integer.)
