(Round your answer to the nearest dollar.) $ Z Need Helo? 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 y = 87 and standard deviation 0' = 28. Note: After 5O years of age, both the mean and standard deviation tend to increase. For an adult (under 50) after a 12-hour fast, nd the following probabilities. (Round your answers to four decimal places.) USE SALT (a) x is more than 60 H (b) x is less than 110 H (c) x is between 60 and 110 H (d) x is greater than 125 (borderline diabetes starts at 125) U Need Help?
