The significant difference between the average formal education of the sample and the surrounding community at the .05 level suggests that the sample is significantly more educated than the community as a whole. Therefore, we can conclude that the sample is more educated than the community. Option A (the null hypothesis should be accepted) and Option B (the research hypothesis should be rejected) are incorrect because they contradict the observed significant difference. Option D (the alpha level is too low) is incorrect because the given information doesn't provide any reason to doubt the appropriateness of the alpha level.
