Multiple Choice

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
-The correct critical value(s) at α = 0.05 (assuming Brand A is group 1 and Brand B is group 2) is(are)

• A) -1.734.
• B) 1.734.
• C) ±2.101.
