a. Repeat the activity using a population proportion 0.60: Take at least five samples of size 10 each, and observe how the sample proportions of the one outcome vary around 0.60, and then do the same thing with at least five samples of size 1000 each.
b. In part a, what seems to be the effect of the sample size on the amount by which sample proportions tend to vary around the population proportion, 0.60?
c. What is the practical implication of the effect of the sample size summarized in part b with respect to making inferences about the population proportion when you collect data and observe only the sample proportion?
