Suppose that you have to schedule and coordinate the various activities for a public health management project. The project can be subdivided into the following ten activities. You can see the project network below. 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 information to answer to the following questions. (a) Fill in the activity nodes. (b) The critical path is If you get more than one critical path, please select the upper one. For example, if you have A-C-G-J (c) The expected optimal completion time is \( E(t)= \) days. (d) Based on the results for the questions (a)-(b), answer the following questions: - How many days the activity \( \mathrm{H} \) can be delayed without increasing the expected project completion time? - Is it possible that the activity \( J \) is delayed without increasing the expected project completion time? (a) Tha followina table shows the calculated expected varlance for each activity. Based on the result for question (b) and the table above, calculate the expected standard deviation for the project cornoletion time. Round the result to 2 decimal places. \[ \sigma(T)=\text { days } \] (I) Assume that the project completion times are normally distributed with \( \mu=E(t) \) (see question \( (c)) \) and \( \sigma=q(T) \) (see question (d)). - Note: If the z-score is less than \( -3.4 \), then assume that the probability is equal to zero. For example, \( P(z \leq-3.85)=0 \) - Note: If the \( z \)-score is greater than \( 3.4 \). then assume that the probability is equal to one. For example, \( P(z \geq 4.00)=1 \). - Notez Do not comvert probabilities to percent. What is the probability that the project will be completed in - 43 days? \( P(T \leq 43)= \) . 34 days? \( P(T \leq 34)= \)
