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 P10, the 10th percentile. This is the bone density score separating the bottom 10% from the top 90%. X X X X P10 P10 P10 P10 The bone density score corresponding to P10 is (Round to two decimal places as needed.)
