please answer all correctly and I will give you a thimbs up! (A through E)

Please round all responses to two decimal places.

A) based on the activity time estimates, the expected times AND variance for each of the activities are ?? (For activities A through D)

B) the expected completion time of the critical path = ?? Weeks.

The expected completion time of the path other than the critical path = ?? Weeks.

C) the variance of the critical path = ?? Weeks.

The variance of the path other than the critical path = ?? Weeks.

D) if the time to complete the activities on the critical path is normally distributed, then the probability that the critical path will be finished in 22 weeks or less = ??

E) D) if the time to complete the activities on the NON - critical path is normally distributed, then the probability that the critical path will be finished in 22 weeks or less = ??
