TE = critical path duration T5 = scheduled project duration Z = probability (of meeting scheduled duration) 2. Given the project information below, what is the probability of completing the National Holiday Toy project in 93 time units? Note the info below is different than the info provided in the text for the National Holiday Toy project. 2 ID Description Predecessor (a) (m) (b) (e 0'19 Variance 1 Design package none 6 12 24 2 Design product 1 16 19 28 3 Build package 1 4 7 10 4 Secure patent 2 24 30 42 5 Build product 2 20 32 50 6 Paint 3, 4, 5 4 7 10 7 Test market 6 13 16 19 NOTE: Start the National Holiday Toy Project problem by drawing a network diagram. Then calculate the weighted average duration of each task-46. Determine the project duration. Calculate the variance of each activity. Then using the CRITICAL path activities variances, use the 2 score formula on page 250 to calculate the 2. Then use the statistical table on page 252 or the Excel function NORM.S.D|ST and find the probability of completion within 93 time units. 2.
