Mean = Variance = Standard Deviation 7. Sketch the second bell curve by showing the mean and standard deviation. 8. What is the data value (raw score) associated with a standard score of 2.08? Determine the percentage greater than this score. Draw the curve and show your complete solution. 9. What is the data value (raw score) associated with a standard score of -1.3? Determine the percentage less than this score. Draw the curve and show your complete solution. 10. What is the range of the data values that would allow 71% of the data to fall within the mean observing symmetry? Draw the curve and show your complete solution. 11. What is the variance of this data set? 12. Are there any outliers with this data set? (Outliers refer to data points that lie beyond 3 standard deviation from the mean).
