Sugar (grams) 6. 15 12 11 8 6- 7 14 20 4 13 Calories 120 200 140 110 140 80 200 120 120 190 190 120 120 The predictive regression equation of the number of calories on the amount of sugar is y= 98.422 + 4.564x, where x is amount of sugar (in grams) and y is calor %3D Give a brief interpretation of the values of a = 98.422 and b = 4.564 in the equation. %3D The value of a = 98.422 means that, on average, the number of calories increases by 98.422 for every one gram increase in sugar represents the number of calories when the amount of sugar is zero means that, on average, the number of calories increases by one for every 98.422 gram increase in sugar
