Use the appropriate applet to construct a simulated null distribution using the MAD statistic. Mark the observed MAD statistic calculated in the previous question on this graph. Th e name of the data set is Aggression.
a. Paste a screen shot or draw your null distribution below with the observed MAD marked and the approximate p-value shaded in.
b. Is the observed statistic out in the tail of this null distribution or is it a fairly typical result?
c. What is the p-value from your simulation? Based on this simulation analysis, would you conclude that the experiment provides strong evidence against the null hypothesis and that there is a significant difference in at least one of the mean aggression scores for the three experimental groups? Explain your reasoning.

The following table provides descriptive statistics on the measurements for aggression:
