Aperson'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 j = 90 and standard deviation o = 28. 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)
