Question

A golf association sets performance standards for golf bals For example, the initial velocity of the ball may not exceed 250 feet per second when messured by an apparatus approved by the association, Suppose a manufacturer introduces a new kind orbalad povides a radomy selected sangle of balsfo testng Based on the mean speed inthe sami·the associado omes upwm1Prousd.4 Einin this conec wrat 4M presen s HA, > 250 t/sec Choose the corect answer below. A. . OC. OD. Assuming that the ball meets he associaton's velocty standard there is a 43% chance that the mean velocity of som e sample would be at least as high as the mean velocity foundinte associations sample.

Explanation / Answer

The p value is 0.43 , this means that there is a 43% chance that what we concluded in our hypothesis is wrong.

hence there is a 43% chance that the mean velocity is less than 250ft/sec

so the correct choice is C
