A normal distribution of scores has a standard deviation of 10. Find the z-scores corresponding to each of the following values: A score of 60, where the mean score of the sample data values is 40. A score that is 30 points below the mean 40. A score of 80, where the mean score of the sample data values is 30.

B. Look the table A, the entry corresponding to the z-score is 0.1587. A. Unstandardize the z-score. X= 60+12*5.2=122.4. 122.4 is much larger than the mean( =60). B. Range= max- min. And here, the first quartile is bigger than the min, so the IQR = Q3-Q1 is smaller than the range. A. For example, N~(2, 20) is also a normal distribution.
