Suppose the USGA wants to compare the mean distances associated with five different brands of golf balls when struck with a driver. A completely randomized design is employed, with Iron Byron, the USGA's robotic golfer, using a driver to hit a random sample of 10 balls of each brand in a random sequence. The distance is recorded for each hit, and the results are shown below, organized by brand.
Golf Ball Test
Brand A: 251.2, 245.1, 248.0, 251.1, 260.5, 250.0, 253.9, 244.6, 254.6, 248.8
Brand B: 263.2, 262.9, 265.0, 254.5, 264.3, 257.0, 262.8, 264.4, 260.6, 255.9
Brand C: 269.7, 263.2, 277.5, 267.4, 270.5, 265.5, 270.7, 272.9, 275.6, 266.5
Brand D: 251.6, 248.6, 249.4, 242.0, 246.5, 251.3, 261.8, 249.0, 247.1, 245.9
Brand E: 248.1, 247.5, 242.2, 245.1, 247.6, 260.1, 247.7, 245.0, 241.6, 249.4
Carry out a complete analysis using ANOVA and a 5% significance level.
