These instructions and the data file are on eCampus:

Download the data file ciass7Data.mat from eCampus. Use a histogram to determine if the data is normally distributed.

Write a function or script that creates an array of N random values from the data set (where N is your sample size) and then computes the sample mean. Use your function to get 200 sample means for a sample size of 10 (you may want to write another script or function to do this). Create a histogram of the sample means. Save the plot.

Follow the same procedure to create a histogram of the sample means for 200 samples of size 25. Save the plot. How do the two plots compare?

Create similar plots for sample sizes of 50 and 100. Save the plots. What does this illustrate about the impact of the sample size on the sampling distribution of the mean?
