2. A person’s blood glucose level and diabetes are closely related. Let x be a random variable measuredin milligrams of glucose per deciliter) 1/10 of a liter) of blood. After a 12- hour fast, the random variable xwill have a distribution that is approximately normal with mean µ = 85 and standard deviation ợ = 25(Source: Diagnostic Tests with Nursing Implications, edited by S. Loeb, Springhouse Press). Note: After 50years of age, both the mean and standard deviation tend to increase. What is the probability that, for an adult(under 50 years old) after 12- hour fast? (a) X is more than 60? (b) X is less than 110? (c) X is between 60 and 110?

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
