Question 3 1 pts On the Sampling Distribution of the Sample Mean (Continuous Population) app in artofstat.com, under Select Population Distribution, choose Skewed from the drop down menu. Change the Sample size (n) to 20. Under "Select how many samples (of size n) you want to simulate drawing from the population:", make sure the button with 1 sample is selected. Now click on Draw Sample(s) - two new graphs will appear. On the top graph labeled Population Distribution it displays the values of mu and sigma. On the middle graph labeled Data Distribution there is a histogram, and the values of x-bar and s are displayed. Now click AGAIN on Draw Sample(s) a FEW times and notice what happens to x-bar, s, mu and sigma. Which of the following statements is correct? The values of x-bar and s change each time because they are statistics, while the values of mu and sigma don't change because they are parameters. The values of x-bar and s change each time because they are parameters, while the values of mu and sigma don't change because they are statistics. The values of x-bar and s change each time because they are computed from the population, while the values of mu and sigma don't change because they are computed from the sample
