  1. Draw an A on A chart.
  2. What is the critical path? What is the project duration?
  3. When the latest can we start activity A1?
  4. When the latest can we start activity A5?
  5. Refer to the critical path you found in b. Assume that every activity is normally distributed. Each activity's mean is given in the table above. Each activity's standard deviation is 20% of its mean (for example, the mean duration of activity A2 is 13 and its standard deviation is 2.6). What is the probability that the project will last more than 80 days?
