Suppose that 10 percent of the people in a certain population have the eye disease glaucoma. For persons who have glaucoma, measurements of eye pressure X win be normally distributed with a mean of 25 and a variance of 1. For persons who do not have glaucoma, the pressure X will be normally distributed with a mean of 20 and a variance of 1. Suppose that a person is selected at random from the population and his eye pressure X is measured.

(a) Determine the conditional probability that the person has glaucoma given that X = x.

(b) For what values of x is the conditional probability in part (a) greater than 1/2?
