What is the probability a project will be completed by the end of period 149 if PERT analysis identified the expected value critical path duration to be 140 periods and the standard deviation to be 5.4. (round to 2 decimals)

8. What is the probability a project will be completed by the end of period 149 if PERT analysis identified the expected value critical path duration to be 140 periods and the standard deviation to be 5.4. (round to 2 decimals) 9. What is the duration of a task that is estimated to take 14 person days if 3 staff are assigned to it for 4 days and one is assigned to finish the work? 10. In a project, approval before proceeding is required at several project stages. While the approval request is being reviewed by senior managers, project staff is basically idle on the project so the project manager has set aside these days for advanced training of project staff. A condensed stakeholder responsibility matrix using the first responsibility coding abbreviations in the workbook is given below. How many calendar days are available in the project for staff training assuming review and approval is completed on average in 2 calendar days each time an approval is required?
