The following data were collected during a study of consumer buying patterns: Click here for the Excel Data File b. Obtain a linear regression line for the data.(Round your intermediate calculations and final answers to 3 decimal places.) c. What percentage of the variation is explained by the regression line? (Do not round intermediate calculations. Round your answer to the nearest whole percent.) Approximately % of the variation in the dependent variable is explained by the independent variable. d. Use the equation determined in part b to predict the expected value of y for x=44. (Round your intermediate calculations and final answers to 3 decimal places.)
