Expected completion time days d. You can do any one of the following at an additional total cost of $1500. If you will save $1000 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. O Yes O NO 2. Reduce job 3 by two days. Yes 3. Reduce job 7 by two days, Yes O No e. What is the probability that the project will take 30 or MORE 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. Enter the probability as a decimal, not a percent. For example, 13.85% would be entered as .1385, not 13.85.) Probability
