First classify the values of grade in DATA2 as High or Low. In particular, if grade is greater than or equal to 831.384 you classify it as High. Otherwise, you classify it as Low. Next, with the classified grade where the values are either High or Low, use the permutation procedure to test the association between the classified grade and q4, where q4 is y variable and the classified grade is x variable. More specifically, set the permutation number to be 467 and set the seed number to be 700. Report three things: 1. p-value (not the range) of the test that you choose. Also, provide your reason why you select that test, 2. Test result and interpret the test result for the association, 3. whether the test result is conclusive or inconclusive. Copy/paste your R codes and answers into Exam2_Ans.RMD file.
