50% of Reese's Pieces candies are orange.

The Reese's Pieces applet lets you simulate draws from a hypothetical population of Reese's Pieces and take data on the orange candies in your sample(s). (This applet was created by Professors Allan Rossman and Beth Chance at Cal Poly, San Luis Obispo.)

If you do not immediately see the "Reese's Pieces" simulation, scroll down the page and in the bottom left-hand corner you need to 'click' where prompted to default to the "Reese's Pieces" simulation.

Use the applet to draw 25 candies and calculate the proportion of orange candies. Do this ten times and write the proportions in the box below. (For example, if 10 out of 25 candies are orange, the proportion would be 10/25 = 0.4.)
