Given the project in the table below, estimate the expected duration of the project and the probability of completing this project in 63 days or less. Consider the cumulative probability of a Z-score value beyond 3.99 with 1.0. The solution should include the following procedures: 1) mean and standard deviation for each activity and 2) mean, standard deviation, and probability at each path (also called chain), and 3) a final answer. (Note: Use the end-of-day convention.)
