To gauge their fear of going to a dentist, a random sample of adults completed the Modified Dental Anxiety Scale questionnaire (BMC Oral Health, Vol. 9, 2009). Scores on the scale range from zero (no anxiety) to 25 (extreme anxiety). The mean score was 11 and the standard deviation was 4. Assume that the distribution of all scores on the Modified Dental Anxiety Scale is approximately normal with µ = 11 and o = 4. Complete parts a through c below. a. Suppose you score a 10 on the Modified Dental Anxiety Scale. Find the z-value for this score. (Round to two decimal places as needed.) 1)
