Assume that a randomly selected subject is given a bone density test. Bone density test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find P 18, the 18th percentile. This is the bone density score separating the bottom 18% from the top 82%. . . . Which graph represents P18? Choose the correct graph below. OD. O C. O B. O A. X X X P 18 X P18 P 18 P 18
