Golf-course designers have become concemed that old courses are becoming obsolete since new technology has given goiters 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 161 golfers be chosen so that their mean driving distance is 247 yards. The population standard deviation is 47.4. Use a 5% significance level Calculate the followings for a hypothesis test where H250 and H 250 (a) The test statistic is (b) The P-Value is The final concluation is A. There is sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 250 8. There is not sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 250 Golf-course designers have become concemed that old courses are becoming obsolete since new technology has given goiters the ability to hit the ball so far.
