A person's level of blood glucose and diabetes are closely related. Let x be a random variable measured in milligrams of glucose per deciliter ( 1/10 of a liter) of blood. Suppose that after a 12-hour fast, the random variable x will have a distribution that is approximately normal with mean =81 and standard deviation of =21. What is the probability that, for an adult after a 12-hour fast, x is between 113 and 121 ? 0.028 0.035 0.936 0.064 0.954 A person's level of blood glucose and diabetes are closely related.
