With randomization techniques we are able to analyze any test statistic we desire. What if we wanted to look at whether there was a difference in the median values of mercury in the Yellowfin tuna compared to the Albacore tuna? Using the Multiple Means applet and the Median option on it, answer parts (f) through (i) of the previous exercise looking at the difference in median mercury levels.

Data from previous exercise

a. What statistic will you use?
b. Use an appropriate applet to carry out a simulation analysis. Report the p-value and strength of evidence.
c. Use the 2SD rule to determine a 95% confidence interval. Interpret the interval, making sure it is clear which parameter (in context) the 95% confidence interval is estimating.
d. Give a full conclusion, including significance, estimation, causation, and generalization.
