An An importand 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 vaies in actual use according to a normal distribution with mean ? = 0.35 and standard deviation ? = 0.039
What proportions of adhesions (±0.001) measured in use are higher than 0.33?
What proportions of adhesions (±0.001) are between 0.33 and 0.47?
