Statement of a problem № m102716



The Old Course at St. Andrews in Scotland is home of the British Open, one of the major tournaments in professional golf. The Hole O Cross Out, known by both European and American professional golfers as one of the friendliest holes at St. Andrews, is the fifth hole, a 514-yard, par 5 hole with an open fairway and a large green. As one reporter put it, "If players think before they drive, they will easily walk away with birdies and pars." The scores on the Hole O Cross Out posted by a sample of 156 golf professionals are presented on the Weiss-Stats site. Use those data and the technology of your choice to decide whether, on average, professional golfers score better than par on the Hole O Cross Out. Perform the required hypothesis test at the 0.01 level of significance. (a). Employ the Wilcoxon signed-rank test. (b). Employ the t-test. (c). Compare your results from parts (a) and (b).
