Dr. Cummings' MGMT300 class wants to develop a new smart classroom using Program Evaluation and Review Technique (PERT). The objective is to be the first to design and market the most innovative smart classroom so as to capture the first mover advantage in the U.S. education market. Dr. Cummings' brilliant students have determined the following activities, precedence relationships, and time estimates in days for the project: Most Likely. Time Optimistic Time Pessimistic Time Activity Immediate Predecessors none 2 5 3 5 12 d 9 10 C. d Question 1 (2 points) What is the expected variance of Activity A? a) greater than 0.5 but less than or equal to 1.0 day b) greater than 1.5 days c) less than or equal to 0.5 days d) greater than 1.0 but less than or equal to 1.5 days Question 2 (2 points) what is the expected duration of the critical path? a) greater than 20 but less than or equal to 25 days Ob) less than or equal to 20 days Oc) greater than 30 days Od) greater than 25 but less than or equal to 30 days Question 3 (2 points) What is the probability that the project will take longer than 28 weeks to complete? a) greater than 0.3 but less than or equal to 0.6 b) less than or equal to 0.1 Oc) greater than 0.1 but less than or equal to 0.3 d) greater than 0.6 but less than or equal to 0.9 Question 4 (2 points) What is the standard deviation of the critical path? a) greater than 2.0 but less than or equal to 3.0 days b) less than or equal to 1.0 days c) greater than 3.0 days O d greater than 1.0 but less than or equal to 2.0 days Question 5 (2 points) What is the expected duration of Activity A? O a) Less than or equal to 2 days Ob) Greater than 2 but less than or equal to 4 days O c) Greater than 4 but less than or equal to 6 days Od) Greater than 6 days
