Activity Std Dev of Activity Time Expected Activity Time Predecessor A 2 11.7 B 3.8 13.7 A 9.2 12.1 B Given the above table, determine the standard deviation of the project critical path. Round your result to 2 decimal places, if applicable. 1 QUESTION 4 The critical path (and only path) of a project has a variance of 9.22 and an expected duration of 45 days, starting on ordinal day o. What should the scheduled date be if a probability of 0.950 is required in finishing on time or early? (Round your answer to one decimal place, if applicable.) QUESTION 5 The scheduled completion date is 50. The expected completion date of the project is 46. The variance of the project critical path is 13.5. Determine the probability of being late. Round your answer to 3 decimal places
