Using permutation test SAS code , do the following:

Trauma data

Metabolic Expenditure

Nontrauma patients: 20.1 22.9 18.8 20.9 20.9 22.7 21.4 20

trauma patients: 38.5 25.8 22 23 37.6 30 24.5

Part A

Build the permutation distribution (using 5,000 permutations)for the rank sum statistic for the Trauma

data used above. Use SAS to fit/overlay a normal curve to theresulting histogram. Compare the mean and

standard deviation of this normal curve that was fit to thepermutation/randomization distribution to the

mu and sigma you found earlier in the homework.

Part B

Compare the one-sided p-value found in this permutationdistribution with the one found in prior questions.
