A person's blood glucose level and diabetes are closely related.Let x be a random variable measured in milligrams of glucose perdeciliter (1/10 of a liter) of blood. Suppose that after a 12-hourfast, the random variable x will have a distribution that isapproximately normal with mean μ = 89 and standard deviation σ =22.
Note: After 50 years of age, both the mean and standarddeviation tend to increase. For an adult (under 50) after a 12-hourfast, find the following probabilities. (Round your answers to fourdecimal 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 at125)
