The following table represents a plan for a project: JOB. PREDECESSOR TIMES (DAYS) NUMBER 30B(5) a m b 1 - 2 3 4 2 1 1 2 3 3 1 4 5 12 4 1 3 4 11 5 2 1 3 5 6 3 1 2 3 7 4 1 8 g 8 5,6 2 4 6 9 8 2 4 12 18 7 3 4 5 1 3,10 5 7 8 b. Indicate the critical path. 1-4-7-10-11 1-2-5-8-9-11 13-6-8-9-11 . What is the expected completion time for the project? Note: Do not round intermediate calculations. Round your answer to 2 decimal places. d. You can accomplish any one of the following at an additional cost of $1,500. If you will save $1,000 for each day that the earliest completion time is reduced, which of the following actions should be taken, if any? 1. Reduce job 5 by two days. Yes No 2. Reduce job 3 by two days. Yes No 3. Reduce job / by two days. Yes No e. What is the probability that the project will take more than 30 days to complete? Note: Use Excel's NORMSDIST() function to find the correct probability for your computed Z-value. Other than the expected completion time you entered in part c above, do not round intermediate calculations. Round "z" value to 2 decimal places and your final answer to 4 decimal places.
