STANDARD NORMAL DISTRIBUTION. In Exercises 1736, 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 A2, round answers to four decimal places.27. Between -1.22 and -2.36 28. Between -0.45 and -2.08 29. Between -1.55 and 1.55 30. Between -0.77 and 1.42 31. Between -2.00 and 3.50 32. Between -3.52 and 2.53 33. Greater than -3.77 34. Less than -3.93 . 35. Between -4.00 and 4.00 36. Between -3.67 and 4.25.
