According to the Internal Revenue Service, the average length of time for an individual to complete (keep records for, learn, prepare, copy, assemble, and send) IRS Form 1040 is 10.12 hours (without any attached schedules).

Find the probability that the 36 taxpayers took an average of more than 12 hours to finish their Form 1040s.
