There appears to be a negative linear relationship between price ($) and overall score. Provide an interpretation of the slope of the estimated regression equation O The slope gives the change in the overall score for every one dollar increase in the price. The slope gives the overall score when the price is $0. Overall Score There appears to be a positive linear relationship between price ($) and overall score. There appears to be no noticeable relationship between price ($) and overall score Use the least square method to develop the estimated regression equation. (Round your numerical values to three decimal places). The slope gives the price when the overall score is O The slope gives the change in the price for every one point decrease in the overall score.
