B-D-F 2) What is the late finish time of task G? week 17 3) What is the slack of task E? 6.5 weeks Pr{ T ≤ 18 } = Pr{ z ≤ 18 - μ Τ σ Τ } = Pr{ z ≤ - } = Pr{ z ≤ 0.973 } = 83.48% 5) What should be the bid date for this project, so that the probability it will be completed on time is at least 95%? Bid Date = μ T + (z (95%) × σ T ) = 17 + 1.645 × 1.056 = 18.7 weeks 6) If you had to crash this project by two weeks, which tasks would you crash each by Tasks D and F for \$44,325 2.
