Hald, Statistical Tables and Formulas (New York: Wiley), 1952.Problem 35 Easy Difficulty Jump To Question The random variable x has a normal distribution with standard deviation 25. It is known that the probability that x exceeds 150 is .90. Find the mean / of the probability distribution.Problem 37 Easy Difficulty Jump To Question 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 / = 11 and 6 = 4. a. Suppose you score a 10 on the Modified Dental Anxiety Scale. Find the z -value for your score. b. Find the probability that someone scores between 10 and 15 on the Modified Dental Anxiety Scale. c. Find the probability that someone scores above 20 on the Modified Dental Anxiety Scale
