Standard Normal Distribution. In Exercises 17-36, 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. In each case, draw a graph, then find the probability of the given bone density test scores. If using technology instead of Table A-2, round answers to four decimal places. 17. Less than -1.23 18. Less than -1.96 19. Less than 1.28 20. Less than 2.56 21. Greater than 0.25 22.
