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 250 yards on average. Suppose a random sample of 200 golfers be chosen so that their mean driving distance is 247.4 yards. The population standard deviation is 48.9. Use a 5% significance level. Calculate the followings for a hypothesis test where Ho: μ = 250 and Hy : μ < 250 : (a) The test statistic is (b) The P-Value is The final conclustion is

Question
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 250 yards on average. Suppose a random sample of 200 golfers be chosen so that their mean driving distance is 247.4 yards. The population standard deviation is 48.9. Use a 5% significance level. Calculate the followings for a hypothesis test where Ho : μ = 250 and Hy : μ < 250 : (a) The test statistic is (b) The P-Value is The final conclustion is O A. There is sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 250 OB. There is not sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 250
