Show all your work (6) Can the 20 week promise to flat owners be met within the budget available? Show all your work. (e) Determine a 19 week schedule for the venture. Is this schedule feasible to the company? Why? (d) The flat owners offered the company to accept a delay in moving into their flats, provided they are compensated by $1,000 each for every week's delay over 20 weeks. Tabulate all feasible options for the company. What is now the cheapest option for the company? Note. Indirect Costs = 80,000 + 1,000 (Duration, in weeks). (e) Suppose that activity F is subject to uncertainty and that the following time estimates are available: Optimistic time: 3, most likely time: 5, and pessimistic time: 7 weeks. Under this new information (1) what is now the critical path? (ii) what is now the mean and standard deviation for the project duration? (iii) what is the probability that the project will be completed in 25 weeks or less. (iv) what is the probability that the project will be completed in 26 weeks or more. (v) what is the completion time corresponding to 67% probability, Z-score - 2.00 - 1.50 - 1.00 -0.4N 0.40 0.50 1.00 Probability 0.0228 0.0668 0.1587 1.25 3.00 0.33 0.50 0.6554 0.69150.8413 0.8944 0.9987 0
