Has the principle of comparison been addressed in this experimental design? A company that manufactures golf balls produces a new type of ball that is supposed to travel significantly farther than the company's previous golf ball. To determine this, 40 new-style golf balls and 40 original- style golf balls are randomly selected from the company's production line on a specific day. The balls are then placed in bag and shaken. A golf pro then O Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball. O Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared. selects a ball and hits it. The distance the ball travels is then measured. The bag is shaken again, and the golf pro selects another ball to hit. She continues this procedure until all 80 of the golf balls are hit. O No, because a placebo ball was not used, a comparison cannot be made to determine if the new ball travels significantly farther. O No, because all of the new type of balls are not hit first, the distances they travel cannot be compared to the distances of the original ball.
