**Simulating Binomial Distribution Applet

This applet simulates drawing samples from a binomial distribution. Users set the population proportion of success (pi), sample size (n), and number of samples. By clicking “Draw Samples,” the applet will draw a sample and display the corresponding sample histogram. Each new sample drawn is added to the previous ones unless the user clicks “Reset” between samples. Users can choose to display the number and proportion of successes above or below a certain value (tail probabilities) by entering a value in the “Num Successes” box and clicking “Count.” The portion of the distribution that meets the condition is highlighted in red, and the proportion of success is given at the bottom of the page. Clicking the inequality sign changes its direction. Clicking “Theo Values” displays the theoretical distribution in green on top of the empirical. Instructions and an activity for this applet can be found in the textbook “Investigating Statistical Concepts, Applications, and Methods” (ISCAM) in Lesson 3.2.2 on page 205.
