Suppose that you have to schedule and coordinate the various activities for an accounting project. The project can be subdivided into the following ten activities. . .

After detailed analysis of the project, you found the expected activity times [in days] for all ten activities. These numbers are incorporated into the project network. Use the given inton'nation to answer to the following questions. c _ _._I F _ |_ : :1: _> : : 4 .| 2 | J! : D | G 3 | J > : .:. \\ 1': : K 3 | a . | 5 f a.

It you get more than one critical path, please select the upper one. For example, it you have ACGJ and BHlJ, then you have to select ACGJ. [c] The expected optimal completion time is E\") | days. {:1} Based on the results for the questions [aJ[bL answer the following questions: . How many days the activity D can be delayed without increasing the expected project oompletion time? . Is it possible that the activity B is delayed without increasing the expected project completion time? (e) The following table shows the calculated expected variance for each activity. Expected Activity Variance A 0.61 B 0.57 C 0.7 D 0.22 E 1.07 F 1.22 G 1.05 H 0.28 0.41 0.43 Based on the result for question (b) and the table above, calculate the expected standard deviation for the project completion time. Round the result to 2 decimal places. o ( T) days (f) Assume that the project completion times are normally distributed with A = E(t) (see question (c)) and o = (T) (see question (d)). . Note: If the z -score is less than - 3.49, then assume that the probability is equal to zero. For example, P(z 4.06) = 1. . Note: Do not convert probabilities to percent. What is the probability that the project will be completed in . 39 days? P(T
