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 ? = 0.41 and standard deviation ? = 0.033
What proportion of adhesions (± 0.001) measured in use are higher than 0.44?
What proportion of adhesions (± 0.001) are between 0.44 and 0.45?
