Expected time for activity = (Optimistic+4Most likely+Pessimistic)/6
Standard deviation = (Pessimistic - Optimistic) / 6 Variance = square of standard deviation
Calculations are as follows:
Critical path is 1--3--5--6--7 with average project duration of 28.84 with variance = .25+.25+.25+1=1.75
Standard deviation of project duration is SQRT(1.75) =1.32
