In order to see which brand of golf balls is best (as measured by distance travelled), an experiment is set up where a mechanical driver hits 5 balls of each of 3 brands. Brand: (Callaway, Callaway, Callaway, Callaway, Callaway, Nike, Nike, Nike, Nike, Nike, Titleist, Titleist, Titleist, Titleist, Titleist) Distance: (296, 264, 269, 269, 277, 269, 269, 259, 274, 265, 298, 298, 310, 314, 293) We initally performed global F-test to this data at a = 0.05 and the result showed that there was a difference in mean distance between brands. Now, we want to perform pairwise t-test for each pair of brands adjusting with the Bonferroni methodology. What is the correct alpha level to be used for each pairwise t-test? O 0.2 O 0.05 O 0.15 O 0.025 O 0.0125 O 0.0167 0.0083
