Using this simulator: https://seeing-theory.brown.edu/probability-distributions/index.html#section3
For this homework problem, you are going to do lots of simulations of the sampling distribution of the mean while systematically changing the underlying population distribution from which samples are being drawn and the sizes of the samples draw. For the first set of simulations, the underlying population distribution will be uniform, which means all values have the same probability of occurring - this looks like the flat rectangle in yellow circled in blue on the figure below. When you load the webpage, the underlying distribution is uniform, so leave it that way for now.
