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 4% and highest 4%, indicating levels that are too low or too high, respectively. Sketch the region containing the lowest 4% and highest 4%. Choose the correct graph below. a Q Q a Q 2p 2p ~ 2a Za z ~ 2a The bone density scores are |_|. (Use a comma to separate answers as needed. Round to two decimal places as needed.)
