Quizplus · Accepted Answer

Confidence limits provide a range within which the true difference in population means is likely to fall with a given level of confidence (in this case, 95%). Therefore, option C is the most appropriate interpretation of the confidence limits in this output. Option A is incorrect because it assumes that the difference in sample means is the same as the difference in population means, which may not be true. Option B is incorrect because it assumes that the confidence limits refer to a minimum value for the population mean, which is not necessarily the case. Option D is incorrect because it implies that the population mean is fixed and has a probability of lying within a certain range, whereas in reality, the population mean is unknown and the confidence interval refers to a range of plausible values for it.
