The following table represents a plan for a project: JOB NO. 1 2 3 4 5 6 7 8 9 10 11 PREDECESSOR JOB (S) 1 1 1 2 m & incor 5, 6 9, 10 TIMES (DAYS) a ND 2 1 4 3 1 1 1 2 2 min 3 5 b. Indicate the critical path. O 1-3-6-8-9-11 O 1-2-5-8-9-11 O 1-4-7-10-11 EM m 3 2 5 4 3 2 8 4 4 47 b 4 3 12 11 5 3 9 96 6 12 5 00 8 c. What is the expected completion time for the project? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Expected completion time days 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 O No 2. Reduce job 3 by two days. Yes O No 3. Reduce job 7 by two days. O Yes O No e. What is the probability that the project will take more than 30 days to complete? (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 your final answer to 4 decimal places.) Probability
