One of the selling points of golf balls is their durability

One of the selling points of golf balls is their durability. An independent testing lab is commissioned to compare the durability of three different brands of golf balls. Balls of each type will be put into a machine that hits the ball with the same force that a golfer uses on the course. The number of hits required until the outer covering cracks is recorded for each ball, with the results are given in the table below. Ten balls from each manufacturer are randomly selected for testing. Brand A B C 310 261 233 235 219 289 279 263 301 306 247 264 237 288 273 284 197 208 259 207 245 273 221 271 219 244 298 301 228 276 Perform an Analysis of variance (ANOVA) to test if GOLF Balls differ from Supplier to Supplier at 5 % significance level. What are the total degrees of freedom? What is the F value? What is the conclusion for this test?
