Question: Dental anxiety study. Psychology students at Wittenberg University completed the Dental Anxiety Scale questionnaire. (Psychological Reports, Aug. 1997.) Scores on the scale range from 0 (no anxiety) to 20 (extreme anxiety). The mean score was 11 and the standard deviation was 3.5. Assume that the distribution of all scores on the Dental Anxiety Scale is normal with \(\mu=11\) and \(\sigma=3.5\)
b. Find the probability that someone scores between a 10 and a 15 on the Dental Anxiety Scale.
c. Find the probability that someone scores above a 17 on the Dental Anxiety Scale.
