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 = 0.35 and standard deviation = 0.037 What proportion of adhesions (± 0.001) measured in use are higher than 0.5? What proportion of adhesions (± 0.001) are between 0.5 and 0.58?
