Create a distribution of 1000 simulated sample statistics we might expect to see if the null hypothesis from part i. is true (check the “Show Shuffle Options” box in the applet and choose the Correlation statistic). State the shape, center, and variability of the distribution of simulated sample statistics and explain why the value of the mean makes sense. Include a screenshot of the distribution belo

Question

Create a distribution of 1000 simulated sample statistics we might expect to see if the null hypothesis from part i. is true (check the “Show Shuffle Options” box in the applet and choose the Correlation statistic). State the shape, center, and variability of the distribution of simulated sample statistics and explain why the value of the mean makes sense. Include a screenshot of the distribution below.
