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 & - 86 and standard deviation of a = 22. What is the probability that, for an adult after a 12-hour fast, x is less than 104? O 0.103 O 0.397 O 0.293 O 0.207 O 0.793 O EI
