The distance is recorded for each hit and the results are, Ask an Expert

Statistics

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.
