Problem

Anna and Apple want to compare the distributions of weights from two different populations A and B, so they take samples from each population. Apple uses the sample standard deviation formula, and finds that sA>sBs_A > s_B. Anna uses the formula for the population standard deviation on the samples. Will Anna find that σA>σB\sigma_A > \sigma_B for the samples? Explain your answer.
