Be sure to round the variance and standard deviation to 2 decimal places. Solve the problem and enter your answers to the questions: 1. What are the critical path activities? 2. What is the expected completion time for the project (#of weeks)? (Your answers need to be within 0.1 of the correct answer) 3. What are the variance and standard deviation for the critical path? (Your answers need to be within 0.1 of the correct answers) 4. What is the probability that the project can be completed in less than 28 weeks? (Round your probability to 3 decimal places.) Be sure to enter your answers as follow: For (1): show the sequence of critical path activities letters. For (2): show the answer is # of weeks.
