If (Activity, Optimistic, Most likely, Pessimistic, Dependency) for the activities are given as follows (A, 1,3,5,-), (B, 2, 4, 6, A), (C, 4, 6, 8, A), (D, 1, 2, 3, B and C), what is slack time for activity B a. Slack time = 3 b. Slack time = 2 c. Slack time = 0 d. Slack time = 1 If (Activity, Time, Dependency) for the activities are given as follows (A, 4,-), (B, 6,-), (C, 2, A and B), what is LS, LF and ST for activity A? a. LS = 1, LF = 6 b. LS = 3, LF = 6 c. LS = 1, LF = 4 d. LS = 2, LF = 6 The if activity A has optimistic, most likely, and Pessimistic values, then the variance of activity A is given by: a. [1/6(P-O)]2. b. [1/36(P-O)]2. c. 1/6[P-O] d. 1/36[P-O] An activity has an optimistic time estimate of 12 days, a most likely estimate of 16 days, and a pessimistic estimate of 30 days. What is the expected standard deviation of the activity? a. Between 1 and 3 days b. Between 2 and 4 days c. Between 3 and 4 days d. Between 4 and 5 days An activity has an optimistic time estimate of 25 days, a most likely estimate of 30 days, and a pessimistic estimate of 35 days. What is the expected duration of the activity? a. Less than 25 days b. Less than 30 days but greater than or equal to 25 days c. Less than 35 days but greater than 30 days d. Less than 35 days but greater than or equal to 30 days Based on the activity network pictured, project duration is: 3 A 5 6 4 D B 6 E a. 14 weeks b. 18 weeks c. 24 weeks d. 15 weeks Based on the activity network pictured, which activities have slack time? 3 5 6 D B 6 E a. Activities A, B, C and E have slack time b. Activity A (1 day slack time) and activity E (5 days slack time) c. Activity B (1 day slack time) and activity E (5 days slack time) d. Activity A (1 day slack time) and activity B (5 days slack time) Based on the activity network pictured, what is the BEST statement? 913 3 A 5 4 4 D B a. Activity A is a critical activity and has 1 day slack time b. Activity C is a critical activity and has 1 day slack time c. Activity B is a critical activity and has 1 day slack time d. Activity A is not a critical activity and has 1 day slack time
