Expected completion time days d. You can accomplish any one of the following at an additional cost of $2,000. If you will save $1,500 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 three days. Yes 3. Reduce job 6 by two days. O No Yes e. What is the probability that the project will take more than 29 days to complete? (Use Excel's NORMSDISTO function to find the correct probability for your computed Z-value. Do not round intermediate calculations. Round value to 2 decimal places and final answer to 4 decimal places.)
