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 P20, the 20th percentile. This is score separating the bottom 20% from the top 80%. Which graph represents P 20? Choose the correct graph below. O A. O B. O c. O D. X P 20 P 20 P 20 P20 The bone density score corresponding to P20 is (Round to two decimal places as needed.)
