58. Using their formulas, for independent samples show that oy, is larger than by, or oy, for either mean separately Provide some intuition for why this happens. (Hint: Notice that if Y is above (below), and I is below (above) 2, then Y2 - Y1 is even further below (above) 2-1. Thus there is the potential for making a larger error in using Y to estimate 2- than in using to estimate or to estimate 42.)
