Let x be a random variable that represents the number of milligrams per deciliter of blood sugar in a diabetes test. Assume that x has a distribution that is approximately normal with a mean of = 120 and estimated standard deviation of = 35. A test result of x > 180 is considered high and is an indication of diabetes. Suppose a doctor uses the average x for two tests taken about a week apart. What can we say about the probability distribution of x ? What is the probability that x >180
