Bone Density Test A bone mineral density test is used to identify a bone disease. The result of a bone density test is commonly measured as a z score, and the population of z scores is normally distributed with a mean of 0 and a standard deviation of 1 a. For a randomly selected subject, find the probability of a bone density test score less than 1.54. b. For a randomly selected subject, find the probability of a bone density test score greater than −1.54. c. For a randomly selected subject, find the probability of a bone density test score between −1.33 and 2.33. d. Find q1 , the bone density test score separating the bottom 25% from the top 75%. e. If the mean bone density test score is found for 9 randomly selected subjects, find the probability that the mean is greater than 0.50.
