Consider the following to answer the question(s) below.
A recent study of two brands of golf balls was undertaken to determine whether there is a difference in the mean distance that the two golf ball brands will fly off the tee. To conduct the test, a robot which swings the club at the same speed and with the same swing pattern each time was used. The following data reflect sample data for a random sample of balls of each brand. We assume that the variances of the two groups are the same.
Brand A: 234 236 230 227 234 233 228 229 230 238
Brand B: 240 236 241 236 239 243 230 239 243 240
-At α = 0.05,

A) we reject the null hypothesis and can conclude that there is a significant difference in the mean distance that the two golf ball brands will fly off the tee.
B) we reject the null alternative hypothesis.
C) we fail to reject the null hypothesis and can conclude that there is no significant difference in the mean distance that the two golf ball brands will fly off the tee.
D) we fail to reject the null hypothesis.
E) we know there is a no difference between the two brands.
