To help consumers in purchasing a laptop computer, Consumer Reports calculates an overall test score for each computer tested based upon rating factors such as ergonomics, portability, performance, display, and battery life. Higher overall scores indicate better test results. The following data show the average retail price and the overall score for ten 13 -inch models. t a) Mayplon a erattar dianrann writh nrire ac the indenendent wariahle (b) What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? There appears to be a negative linear relationship between price ( $ ) and overall score. There appears to be no noticeable relationship between price (\$) and overall score. There appears to be a positive linear relationship between price (\$) and overall score. (c) Use the least squares method to develop the estimated regression equation. (Round your numerical values to three decimal places). y^ (d) Provide an interpretation of the slope of the estimated regression equation. The slope gives the change in the overall score for every one dollar increase in the price. The slope gives the price when the overall score is 0 . The slope gives the overall score when the price is $0. The slope gives the change in the price for every one point decrease in the overall score. The slope gives the change in the price for every one point increase in the overall score. (e) Suppose the price for another laptop that Consumer Reports tested was $1,000. Predict the overall score for this laptop using the estimated regression equation developed in part (c). your answer to one decimal place.)
