FINDING BONE DENSITY SCORES. In Exercises 37-40 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. In each case, draw a graph, then find the bone density test score corresponding to the given information. Round results to two decimal places.

40) Find the bone density scores that are the quartiles Q1, Q2, and Q3.
