Golf-course designers have become concerned that old courses are becoming obsolete since new technology has given golfers the ability to hit the ball so far. Designers, therefore, have proposed that new golf courses need to be built expecting that the average golfer can hit the ball more than 255 yards on average. Suppose a random sample of 163 golfers be chosen so that their mean driving distance is 255.3 yards, with a standard deviation of 42.8. Conduct a hypothesis test where H0: \mu = 255 and Ha: mu > 255 by computing the following:
(a) what is the test statistic (b) what is the p-value
