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 198 golfers be chosen so that their mean driving distance is 225.1 yards. The population standard deviation is 49.5. Use a 5% significance level. Calculate the followings for a hypothesis test where Hoμ = 230 and H₁ μ< 230 : (a) The test statistic is (b) The P-Value is The final conclustion is OA. There is sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 230 B. There is not sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 230

7:48 1 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 198 golfers be chosen so that their mean driving distance is 225.1 yards. The population standard deviation is 49.5. Use a 5% significance level. Calculate the followings for a hypothesis test where Ho μ = 230 and H₁ : µ< 230 : : (a) The test statistic is (b) The P-Value is The final conclustion is A. There is sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 230 B. There is not sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 230
