The values had a correlation of 0.542, indicating that gas mileage decreases with increasing car weight. Describe how you would use a randomization test to estimate a p-value for the correlation value. ANSWERS MAY VARY. SAMPLE

Answer to Question 1

USE A COMPUTER TO COMPUTE THE CORRELATION FOR ALL PERMUTATIONS OF CAR WEIGHTS AND GAS MILEAGES. PLOT THE CORRELATIONS AS A RANDOMIZATION DISTRIBUTION. THE P-VALUE IS THE PROPORTION OF THE PERMUTATIONS THAT HAVE AN ABSOLUTE CORRELATION OF 0.542 OR GREATER.
