Psychology students at a university completed the Dental Anxiety Scale questionnaire. Scores on the scale range from 0 (no anxiety) to 20 (extreme anxiety). The mean score was 13 and the standard deviation was 3.5. Assume that the distribution of all scores on the Dental Anxiety Scale is normal with 11 = 13 and 5:35. Complete parts a through c. 3 Click here to View a table of areas under the standardized normal curve. Table of Normal Curve Areas a. Suppose you score a 16 on the Dental Anxiety Scale. Find the z-value for this score. Z (Round to the nearest hundredth as needed.) b. Find the probability that someone scores between 12 and 17 on the Dental Anxiety Scale.
