The physics department has three placement tests. The mean is 100 on all three tests. On the Classical test, the standard deviation is 16. On the EM test, the standard deviation is 10. On the Quantum test, the standard deviation is 12.
Rank the following five exam papers (with 1 being the best). (If two are equal ranking, give them the same number, then skip the next place, like 1 2 2 4 5 represents two papers tied for 2nd.)
Lou scored 88 on the Quantum test
Chris scored 97.5 on the EM test
Roger scored 88 on the Classical test
Tim scored 76 on the Classical test
Joyce scored 92 on the C
