Assume that a randomly selected subject is given a bone density test. These test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the bone density test scores that can be used as cutoff values separating the lowest 18% and highest 18%, indicating levels that are too low or too high, respectively. Sketch the region. Choose the correct graph below. The bone density scores are . Round to two decimal places as needed.
