It is often suggested that project managers obtain three time estimates for work units that have significant uncertainty associated with their time estimates. Assume you have collected three time estimates for each activity for a performance monitoring system at an international airport baggage handling system. Your cost estimate worksheet suggests the following:

Project estimate: 50 hours

Project standard deviation: 18 hours

Based on this information and assuming 3 standard deviations from the mean to include approximately 99.75% of the area under the normal distribution curve, calculate:
