MaxFlight produces golf balls with a mean driving distance of 295 yards. Its quality control program involves taking periodic samples of 50 golf balls to monitor the manufacturing process.

Quality assurance procedures call for the continuation of the process if the sample results are consistent with the assumption that the mean driving distance for the population of golf balls is 295 yards; otherwise the process will be adjusted.

Assume that a sample of 50 golf balls provided a sample mean of 293 yards. The population standard deviation is believed to be 12 yards.

Perform a hypothesis test, at the .01 level of significance, to help determine whether the ball manufacturing process should continue operating or be stopped and corrected.

Suppose we are comparing the mean driving distance between 2 types of golf balls. At the same location, the same golfer drives ball A 40 times and ball B 40 times. For the ball A sample there is a mean of 242 yards with a standard deviation of 41 yards. For the ball B sample there is a mean of 265 yards with a standard deviation of 48 yards. Does the data show that there is a difference in the...

A plant manager is interested in developing a quality-control program for an assembly line that produces light bulbs. To do so, the manager considers the quality of the products that come from the line. The light bulbs are packed in boxes of 12, and the line produces several thousand boxes of bulbs per day. To develop baseline data, workers test all the bulbs in 100 boxes. They obtain the following results: Defective Bulbs/Box Boxes 0 68 1 27 2 3...

A golf equipment manufacturer would like to convince members of a club that its golf balls travel farther than those of a rival. For the comparison, twelve golfers were randomly selected from the club to each drive a ball from this manufacturer and from the rival. The results show the distance traveled, in yards. The complete set of results is provided below: Should every golfer hit the rival ball first and then the manufacturer’s ball second? Explain your answer. State...

A sporting goods manufacturing company wanted to compare the distance traveled by golf balls produced using each of four different designs. Ten balls were manufactured with each design and were brought to the local golf course for the club professional to test. The order in which the balls were hit with the same club from the first tee was randomized so that the pro did not know which type of ball was being hit. All 40 balls were hit in...
