Golf course designers have become concemed that old courses are becoming obsolete since new technology has given golfers the ability for the ball so far Designers, therefore, nave proposed that new golf courses need to be built expecting that the average golferican hit the ball more than 25 yards on average. Suppose a random sample of 108 golfers te chosen so that their meant driving distance is 263 yards The population standard deviation is 47 2. Use a significance level Calculate the followings for a hypothesis test where Ho255 and H <255 (a) The test statistics b) The Values The final conclusion is A. There is not suicient evidence to warrant rejection of the claim that the mean driving distance is equal to 255 B. There is sufficient evidence to warrant rejection of the claim that the mean driving distance is equal to 255

45 people are randomly selected and the accuracy of their wristwatches is checked, with positive errors representing watches that are ahead of the correct time and negative errors representing watches that are behind the correct time. The 45 values have a mean of 100sec and a population standard deviation of 230 sec Use a 0,01 significance level to test the claim that the population of all watches has a mean of Osec use a two-sided alternative) The test statistics The p values The final conclusion is A There is not sumcient evidence to warrant rejection of the claim that the mean is equal to 0 B: There is suficient evidence to warrant rejection of the claim that the mean is equal to

10 people are randomly selected and the accuracy of the wristwatchesi checked with positive errors representing watches that are ahead of the correct time and negative enos representing watches that are behind the correct time. The 10 values have a mean at isecand a standard deviation of 180sec Use a 0:02 significance level to test the claim that the population of all watches has a mean of sec The test statistics The Values The final conclusion is A. There is not sufficient evidence to warrant rejection of the claim that the mean is equal to There is suficient evidence to warrant rejection of the claim that the mean is equal to 0
