The shape of a given population distribution is normal with a mean of μ = 85 and a standard deviation of o= 6.5. For these parameters, transform a raw score of X = 100.5 into its corresponding z score. Round to the nearest tenths place if a fraction. The z score is: O 2.4 -3.7 -3.4 09.2 The correct z-score is not listed.
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)
