Assume that a randomly selected subject is given a bone density test. Those 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. O A. O B. O c. OD. O The bone density scores are. (Use a comma to separate answers as needed. Round to two decimal places as needed.)
