The following questions are based on a distribution of scores with M = 84 and the SD = 4.25. (Sometimes drawing a picture will help see what’s required.)  What is the probability of a score falling between a raw score of 76 and 82? What is the probability of a score falling above a raw score of 80? What is the probability of a score falling between a raw score of 86 and 88? What is the probability of a score falling below a raw score of 79?
