Sampling Distribution Activity (Proportions)


Last week's activity on the sampling distribution of sample proportions also worked out smoothly. The five colors of Skittles were assumed to be evenly distributed. For example, the proportion of green candies would be 0.20.  In our class of 30 cups, we found that the expected value to be around 0.189. In this case, we did not have enough evidence to doubt that the colors are not evenly distributed.
