The cоmputer science depаrtment wаnts tо estimаte the average length оf time it takes students to complete a computer project correct to within 5 hours with probability 0.96. They do not have an estimate of the standard deviation of the times, but they remember that last year the shortest time needed to complete the project was 6 hours and the longest time was 36 hours. Given this information, an appropriate estimate of the standard deviation of the length of time required to complete the computer project would be:
