Click on the button "5 samples" to choose 5 separate samples from the population, calculate their means and plot their means. Click on the button "20 samples" to choose 20 separate samples from the population, calculate their means and plot their means. Each time either of these buttons are pressed the action is carried out for two different samples sizes. Change the sample sizes by inputting their sizes in the input boxes. What do you notice about the shapes of the distributions of the sample means? What do you notice about the mean of the distributions of the sample means? What do you notice about the standard deviations of the distributions of the sample means? Can you explain why these relationships exist?
