Random samples of people from Maine, Texas, and Rhode Island have been given a scale that measures their support for a new health care policy. Maine residents average 10.2 with a standard deviation of 5.3. Texans average 10.2 but their stansdard deviation is 1.8. Rhode Island residents average 10.2 with a standard deviation of 2.6. How could these results be dealt with appropriately? a. test the difference in the sample means for statistical sifgnificance b. since the sample means  are the same value, there is no need to conduct any tests; these results cannot be significant c. a two-tailed test of significance is called for d. a test of significance with a very high alpha level is called for
