Using beta distribution calculate the estimated duration for a task the could take as long as 14.5 hours, but most likely will take 12 hours. However, it could be done as soon as 11.5 hours. Please round to the nearest half hour 12.5 hours 13 hours 14.5 hours 13.5 hours Question 2 1 pts The Early finish for a task is calculated using which formula ES-Dur =EF LS+ Dur =EF ES+Dur=EF ES+LS=EF You are determining the float for a task and you know that the ES is 4 days, EF is 7 days, and LF is 9 days. What is the float for this task? 4 days 3.5 days 0 days 2 days Question 4 1 pts What two equations will provide you the float for a task? LFEF=Float LF+Dur=Float LS+ES = Float LS-ES=Float A summary of a subset of activities in the overall network diagram is know as a: Concurrent Activity Hammock Activity Merge Activities Summary Bar Question 6 1 pts T or F: Backward pass calculates the late finish times for all uncompleted network activities. The latest finish dates are determined by working backward through each activity. True False
