Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (Each pair of variables has a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. The caloric content and the sodium content (in milligrams) for 6 beef hot dogs are shown in the table below. Calories, x 160 180 130 130 70 190 (a) x = 170 calories (b) x = 80 calories Sodium, y 410 460 320 380 240 510 (c) x = 150 calories (d) x = 220 calories Find the regression equation. y =x +0) (Round to three decimal places as needed.)
