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 150 180 130 190 (a) x = 170 calories (b) x = 100 calories Sodium, y 415 465 330 380 270 530 (c) x = 140 calories (d) x = 210 calories . .. Find the regression equation. y = [ x +0 (Round to three decimal places as needed.)
