Recently, you were assigned to manage a project for your company. You have constructed a network diagram depicting the various activities in the project (shown below to the right). In addition, you have asked your team to estimate the amount of time that they would expect each of the activities to take. Their responses are shown in the following table: Q a. What is the expected completion time of the project? Time Estimates (days) Activity Optimistic Most Likely 45 ABCD 6 7 Pessimistic 10 9 10 7 1 4 85 E 5 7 9 The expected completion time is days.

A company is willing to develop their rocket before the end of current financial year which is now 28 weeks away. The chief engineer of the company has decided to use PERT technique in order to plan, schedule and control program of development for the data given in table below. What is the probability that the program will be completed by the end of the current financial year? (all durations are in weeks).

The project described in the following table has just begun. It is scheduled to be completed in 11 weeks.Use Table B1 and Table B2.  Activity Estimated Time(weeks) Standard Deviation(wks.) 1-2 4 0.70 2-4 6 0.90 1-3 3 0.62 3-4 9 1.90    a. If you were the manager of this project, would you be concerned? (Round your intermediate calculations to 2 decimal places and "Probability" values to 4 decimal places.)            because the probability of finishing on schedule is only about . b. If there is a penalty of $5,000 a week for each week the project is late, what is the probability of incurring a penalty of at least $5,000? (Round your intermediate calculations to 2 decimal places and "Probability" values to 4 decimal places.)  Probability            Have worked this with various formulas and all come back wrong.  Where am I making a mistake
