A person’s blood glucose level and diabetes are closely related.
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 μ = 83 and standard deviation σ = 21.
x is more than 60
x is less than 110
x is between 60 and 110
x is greater than 125 (borderline diabetes starts at 125)
Porphyrin is a pigment in blood protoplasm and other body fluids that is significant in body energy and storage. Let x be a random variable that represents the number of milligrams of porphyrin per deciliter of blood. In healthy circles, x is approximately normally distributed with mean μ = 43 and standard deviation σ = 12. Find probabilities.
x is less than 60
x is greater than 16
x is between 16 and 60
x is more than 60 (This may indicate an infection, anemia, or another type of illness.)
