Question

A golf association sets performance standards for golf balls. For example, the initial velocity of the ball may not exceed 250 feet per second when measured by an apparatus approved by the association. Suppose a manufacturer introduces a new kind of ball and provides a randomly selected sample of balls for testing. Based on the mean speed in the sample, the association comes up with a P-value of 0.22. Explain in this context what the 22% represents. H_0: mu lessthanorequalto 250 ft/sec H_A: mu > 250 ft/sec Choose the correct answer below. Assuming that the ball meets the association's velocity standard, there is a 22% chance that the mean velocity of some sample would be at least as high as the mean velocity found in the association's sample. Assuming that the ball does not meet the association's velocity standard, there is a 22% chance that the mean velocity of some sample would be at least as high as the mean velocity found in the association's sample. There is a 22% chance that the mean velocity of all such balls is greater than 250 ft/sec. Assuming that the ball meets the association's velocity standard, there is a 22% chance that the mean velocity of some sample would be lower than the mean velocity found in the association's sample.

Explanation / Answer

Solutions: Option A

A.Assuming that the ball meets the association's velocity standard ,there is a 22% chance that the mean velocity of some sample would be atleast as high as the mean velocity found in the association's sample.

explanantion:

whenever ball meets velocity standard , the sample will be as high as the mean velocity
