Random samples of men and women have been given a scale that measures their support for gun control. Men average 10.2 with a standard deviation of 5.3. Women also average 10.2 but their standard deviation is 1.8. How could these results be dealt with appropriately?
A) Test the difference in the sample means for statistical significance.
B) Since the sample means are the same value, there is no need to conduct any tests; these results cannot be significant.
C) A one-tailed test of significance is called for.
D) A test of significance with a very high alpha level ( α 0.10) is called for.
