A regression analysis between weight (y in pounds) and height (x in inches) resulted in the following least squares line: [pic]= 120 + 5x. This implies that if the height is increased by 1 inch, the weight, on average, is expected to:
A. increase by 1 pound
B. decrease by 1 pound
C. increase by 5 pounds
D. increase by 24 pounds
