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 152 golfers be chosen so that their mean driving distance is 229.9 yards. the population standard deviation is 41.4. use a 5% significance level.
