+-2 points DevoreStat9 6.E.036 My Notes Ask Your Teache when the population distribution is normal, the statistic median IX1-, . . . , Xn-113/0.6745 can be used to estimate o. This estimator is more resistant to the effects of outliers (observations far from the bulk of the data) than is the sample standard deviation. Compute both the corresponding point estimate and s for the data below. (Round your answers to three decimal places.) 24.48 25.81 26.27 26.44 26.68 27.17 27.33 27.56 27.76 27.96 28.01 28.06 28.30 28.51 28.52 28.89 29.13 29.15 29.49 30.21 point estimate sample standard deviation s-
