Am I Normal?

Level pending

Bob recently took the Free Academic Koalification Exam (FAKE), in which one has to solve 5 math problems in the least amount of time. Bob completed the exam in about \(84.25\) seconds.

The mean time for all people taking the FAKE is \(100\) seconds, and the standard deviation is \(10.5\) seconds.

Assuming the times for the FAKE are approximately Normal distributed, which of the following is closest to the percent of people who completed the FAKE faster than Bob did?

(For your convenience, here is a z-score table).
