Goal(s): Apply proportions to the normal distribution. Focus is on one tail of a distribution. Related to percentile ranking and hypothesis testing.
How: Each time that you are shown two normal distributions, pick the one with the correctly shaded region. Make 30 quick decisions, with immediate feedback.

Proportion from the Left Tail
A percentile rank indicates the percentage of the population a person scored above. On a number line, the percentile ranking indicates the percentage of scores to the left (i.e., less than) a given value. A percentile ranking is written as a number, with a small "th" at the top right. Mariana's percentile for running speed among girls her age is 77th. This means that her running time is faster than 77% of the other girls.
Proportion from the Right Tail
Sometimes the focus is on the "top" performers. For example, the CSUs aim to accept the top .25 of the graduating high school seniors. Looking at a normal distribution, we would see it shaded inward from the right tail.
Z score
The Z score indicates the number of standard deviations a value is away from the mean.
