Note: the next question will concern this same problem 49 25 56 Task B D Normal Cost $500 5700 $300 $600 Crash Cost $2,600 $1.900 $700 $2.400 Normal Crash Time Time (days) (days) 4 1 7 $ 6 4 $ 3 Task A Task B Task Task D Question 10 5 pts This is the same problem as the last one, which task would you shorten second? B7 44 05 56 Task A B D Normal Cost S500 5700 $300 $600 Crash Cost $2,600 S1.900 $700 $2.400 Normal Crash Time Time (days) (days) 4 7 S 6 5 4 Task A Tasks A and C Tasks B and C Tasks B and D Task D D Question 11 5 pts In a PERT problem our project has an expected completion time of 300 days and a standard deviation of 10 days. What is the probability of us finishing in 325 days or sooner? The normal curve data that we have been using comes from the chart on page 866 (Table A in Appendix B). 93.3% 95.1% 96.396 0.99.4% 99.8% Question 12 5 pts In a PERT problem our project has an expected duration of 90 days and a standard deviation of completion of 3 days. When will we be finished with 93.3% probability? Again, the normal curve data that we have been using comes from the chart on page 866 (Table Ain Appendix B). o 91.6 days O 94.5 days 98.7 days 99.2 days 100.6 days
