Marjorie collects data from 10 different samples and computes the sample means. She finds that her sample means vary a great deal from one sample to the next. What does this indicate? ICI If the sample means vary a great deal, the samples must not be representative of the population. C If the sample means vary a great deal, the samples must be too small. C If the sample means vary a great deal and the samples are not biased, Ricky must have calculated the means incorrectly. ICI Since the sample means are only estimations of the populations mean, a large variation among the sample means is to be expected
