Use the following problem statement to answer questions 1-6. BK Home, a homebuilding company, plans to build a new shopping center. A consultant for the company has constructed a project network and estimated activity times, in weeks. The consultant found the following critical path: ACD. The expected activity times of A,C and D are 10,5, and 5 weeks. The variances of A,C and D are 3,1 , and 2 . Round to four decimal places. [Note: z=(X t)/, where X= given value; t= expected project completion time; = standard deviation of the project completion time] APHEUS Standard Normal Distribution Table The table entries represent the are under the standard normal curve from 0 to the specified value of z.
