1) An important measure of the performance of a locomotive is its "adhesion," which is the locomotive's pulling force as a multiple of its weight. The adhesion of one 4400- horsepower diesel locomotive model varies in actual use according to a Normal distribution with mean u=0.37 and standard deviation o-0.04. What proportion of adhesions are between 0.40 and 0.50? 2) Use Table A to find the proportion of observations from a stand Normal distribution that falls in the following regions. In each case, sketch a standard Normal curve and shade the area representing the region. a. z 1.77 d. -2.25
