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 ? = 82 and
standard deviation ? = 27. Note: After 50 years of age,
both the mean and standard deviation tend to increase. For an adult
(under 50) after a 12-hour fast, find the following probabilities.
(Round your answers to four decimal places.)
(a) x is more than 60
(b) x is less than 110
(c) x is between 60 and 110
(d) x is greater than 125 (borderline diabetes starts at
125)
