HURRY NEED THIS ASAP. A company that manufactures golf Pointsproduces 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 Pointsand 40 original-style golf Pointsare randomly selected from the company’s production line on a specific day. A golf pro then randomly selects a ball, not knowing the type of ball, and hits it. The distance the ball travels is then measured. He continues this procedure until all 80 of the golf Pointsare hit. At the end of the session, the mean distance traveled for the new type of golf ball was found to the significantly greater than the mean distance for the original-style golf ball.
Which of the following is a valid conclusion?

Inferences can be made about all the golf Pointsproduced on that day, and the conclusion can be made that the new type of golf Pointstravel farther than the original type of golf ball for this golf pro.
Inferences can be made about all the golf Pointsproduced on that day; however, a conclusion cannot be made that the new type of golf Pointstravel farther than the original type of golf ball for this golf pro.

Answer:

The conclusion based on the mean of the ball and the distance traveled is D. Inferences cannot be made about all the golf balls produced on that day.

How to deduce the inference?

From the information given, a golf pro randomly selects a ball, not knowing the type of ball, hits it and end of the session, the mean distance traveled for the new type of golf ball was found to be greater than the mean distance for the original-style golf ball.

In this case, inferences cannot be made about all the golf balls produced on that day; however, the conclusion can be made that the new type of golf balls travel farther than the original type of golf ball for this golf pro.
