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 x₁ represent the contrast ratio rating, x₂ represent the resolution rating, and y represent the overall rating.) Save the DataFile to your computer and use R-studio to create the regression
equation.
