Exercise 19: Sample Size

Exercise 19: Sample Size. Part One. Explore how sample size affects the distribution of sample proportions This was achieved by first taking random samples 20 times when n=10 and then taking 20 random samples where n=40. These random samples were then summarized as sample statistics (p-hat). .
