WIN uses a high-technology manufacturing process to produce golf balls with a mean driving distance of 294 yards. WIN’s quality control program involves taking periodic samples of 50 golf balls to monitor the manufacturing process.  The quality control team selected alpha = .05 as the level of significance for the test to determine that the mean driving distance is 294 yards. The assumed population standard deviation is 10.
