26. Medical: Blood Protoplasm Porphyrin is a pigment in blood protoplasm and other body fluids that is significant in body energy and storage. Let x be a random variable that represents the number of milligrams of porphyrin per deciliter of blood. In healthy adults, x is approximately normally dis- tributed with mean u = 38 and standard deviation o = 12 (see reference in Problem 25). What is the probability that (a) x is less than 60? (b) x is greater than 16? (c) x is between 16 and 60? (d) x is more than 60? (This may indicate an infection, anemia, or another type of illness.)
