1. Suppose the USGA wants to compare the mean distance associated with four diFferent brands of golf balls when struck with a driver. A completely randomized design is employed wilh Iron Byron, the USGA's robotic golfer, using a driver to hit a random sample of ID balls of each brand in a random sequence. 'lhe distance is recorded for each hit and the results are shown in the table below organized by brand. Results of Completely Randomiled Design: Iron Byron Driver a. Set up the hypothesis tests to compare the mean distances of the four brands. b. At re .10 level of signicance, are all of the mean driyi ng distances re same? c. If not, are any of the mean driving distances the same
