Question

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. a golf pro randomly selects a ball, not knowing which type is chosen, and hits it. the difference in mean distances traveled (new - original) for the samples was 4.8 feet. assuming there is no difference in distance traveled between the two types of golf balls, 200 simulated differences in sample means are displayed in the dotplot. dotplot image description: simulated differences in mean distances of golf balls, x - axis: difference in mean distance (new - original) with values from - 6 to 6, y - axis: frequency 1 question part ence in mean distances from the samples, is there convincing evidence that the new golf ball travels farther than the original golf ball? options: yes, because a difference in mean distances of 4.8 feet or more occurred only 6 out of 200 times, meaning the difference is statistically significant and there is convincing evidence the new golf ball travels farther than the original golf ball. yes, because a difference in mean distances of 4.8 feet or less occurred 194 out of 200 times, meaning the difference is statistically significant and there is convincing evidence the new golf ball travels farther than the original golf ball. no, because a difference in mean distances of 4.8 feet or more occurred 6 out of 200 times, meaning the difference is not statistically significant and there is not convincing evidence the new golf ball travels farther than the original golf ball. no, because a difference in mean distances of 4.8 feet or less occurred 194 out of 200 times, meaning the difference is not statistically significant and there is not convincing evidence the new golf ball travels farther than the original golf ball.

Explanation:

Answer:

Yes, because a difference in mean distances of 4.8 feet or more occurred only 6 out of 200 times, meaning the difference is statistically significant and there is convincing evidence the new golf ball travels farther than the original golf ball.
