Quizplus · Accepted Answer

The summary suggests that there are three populations (A, B, and C) being compared and that the mean of population B appears to be larger than the mean of population A, and the mean of population C appears to be larger than the mean of population A. There is no mention of population D, so option C is not correct. Option A is not correct because it suggests that none of the means differ significantly, which is not supported by the summary. Option D is not correct because it only mentions the difference between population A and B, and does not account for the comparison between population A and C. Therefore, the best choice is B.
