1 5.3 Normal Distributions: Finding Values
Key Concepts: Finding a z-score given an area below the Standard Normal Curve Transforming a z-score to an x-value Finding a specific data value for a given probability

2 5.3 Normal Distributions: Finding Values
In previous sections, we were asked to find the percentage of observations that lie above/below a given value or between two values. In this section, we will be given the percentage and asked to find the corresponding data value or values. Finding z-scores #2 p. 257 #4 What if the cumulative area = 0.95? What if the cumulative area = ? #12

3 5.3 Normal Distributions: Finding Values
More practice finding z-scores #26 p. 257 #30 p. 258 We can use what we have learned to convert from z-scores to data values. #34 p (Kidney Transplant Waiting Times) #36 p (Ice Cream Consumption) Challenge! #42 p (Statistics Grades)
