Using the Graphing Calculator to Find Area Under a Curve

To find the area between 2 z-scores… 1. Press 2nd, Vars, 2 (normal cdf). 2. Enter the 2 z- scores, separated by a comma. 3. The answer is the area between the z-scores. To find the area between 2 z-scores…

To find the area under a curve using standard numbers 1. You can use the x-value, mean, and standard deviation to specify. 2. Enter 2nd, Vars, normal cdf on your calculator. 3. The 1st number and 2nd number, separated by a comma represent the x- value range. 4. The 3rd number is the mean. 5. The 4th number is the standard deviation. To find the area under a curve using standard numbers
