A person's blood glucose level and diabetes are closely related. Letxbe a random variable measured in milligrams of glucose per deciliter(1/10 of a liter)of blood. Suppose that after a12-hourfast, the random variablexwill have a distribution that is approximately normal with mean=83and standard deviation=30.Note:After 50 years of age, both the mean and standard deviation tend to increase. For an adult(under 50)after a12-hourfast, find the following probabilities. (Round your answers to four decimal places.)

(a)xis more than 60 :__________

(b)xis greater than 16 :________

(c)xis between 16 and 60 :________

(d)xis more than 60 (This may indicate an infection, anemia, or another type of illness.) :________
