Areas In Intervals

Activity Overview

Students use several methods to determine the probability of a given normally distributed value being in a given interval. First, they use the Integral tool to find areas under the curve and to the left of given values. Students continue the activity to find probabilities for which the corresponding area is greater than a given value, and then they conclude the activity by finding areas between z scores.
