A person’s blood glucose level 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 µ = 90 and standard deviation σ = 20. (Round your answers to three decimal places.)

(A) (3 points) What is the probability that X is greater than 90? (B) (3 points) What is the probability that X is between 70 and 110? (C) (3 points) What is the probability that X is between 55 and 100? (D) (3 points) What is the probability that X is less than 50 or greater than 90? (E) (3 points) What is the probability that X is less than 85?
