The united states golf association (usga) sets performance standards for golf balls. for example, the mean initial velocity of the ball may not exceed 250 feet per second when measured by an apparatus approved by the usga. suppose a manufacturer introduces a new kind of ball and provides a sample for testing. based on these data, the usga comes up with a 95% confidence interval for the mean initial velocity from 240.8 to 259.9 feet. what does this say about the performance of the new ball?
