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 230 yards on average. Suppose a random sample of 178 golfers be chosen so that their mean driving distance is 227.8 yards. The population standard deviation is 45.5. Use a 5% significance level. Calculate the followings for a hypothesis test where Ho : y = 230 and H1 : 4 < 230 : (a) The test statistic is (b) The P-Value is The final conclustion is A. There is not sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 230 B. There is sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 230
