The G&E Company is preparing a bid to build the new 47,000-seat Shoreline baseball stadium. The construction must start on Jan 01 2022, and be completed in time for the finals of the 2024 season. A penalty clause of $250,000 per week of delay beyond October 1st, 2024 is written into the contract. George Earnings, the president of the company, expressed optimism at obtaining the contract and revealed that the company could net as much as $3 million on the project. He also said if they succeed, the prospects of future projects are bright since there is a projected renaissance in building classic ballparks with modern luxury boxes.

(a) What is the shortest project completion time among the three possible scenarios? (For example: enter 15 for 15 months) (b)What is the longest project completion time among the three possible scenarios? (For example: enter 15 for 15 months) (c)What is the expected project completion time? (A weighted average among the three scenarios with probabilities specified in the table) (For example: enter 13.64 for 13.64 months)
