A persons blood glucose levels and diabetes are closely related. Let x be a random varibale measured in milligrams of glucose per deciliter (1/10 of a liter) of blood. After a 12 hour fast, the random variable x will have a distribution that is approximatly normal with a mean of 85, and a standard deviation 25. Note: after 50 years of age, both the mean and the stanadard deviation tend to increase. Find the following probabiltites of an adult (under 50 years of age) after a 12-hour fast: (round your answer to four decimal places.) also draw the schematic diagrams for the four condition..
1. x is more than 60
2. x is less than 110
3.x is between 60 and 110
4. is is greater than 140
