What is the Expected Time for an activity on a PERT network if it has the following time estimates: Optimistic = 3.5 weeks, Most Likely = 6.0 weeks, and Pessimistic = 8.5 weeks? 53 6,0 O 50 120 y Suppose that the last four months of sales were 11, 12, 18, and 12 units, respectively. Suppose further that the last four forecasts were 6, 13, 10, and 13 units, respectively. What is the Mean Absolute Deviation (MAD) value of these forecasts?

O $700 O $1275 A project being analyzed by PERT has 42 activities, 15 of which are on the critical path. If the estimated time along the critical path is 115 days, and the sum of variances along the critical path is 64 days, what is the probability that the project will take at least 125 days to complete? Some Z values from the table: 0.20 – 58.8%:0.25 -60%: 1.04 – 85%: 1.28 – 90%: 165 = 95%: 206 = 9821 82.1 89.4% O 17.99 Near zero 10.6%
