A$)$ The expected completion time of the project $=\_\_\_$ days $($round your response to two decimal places$).$

B$)$ The activities that represent the project's critical path are $\_\_\_\_\_\_\_\_\_\_\_.$

C$)$ If the time to complete the activities on the critical path is normally distributed, then the probability that the critical path will be finished in $53$ days or less $=\_\_\_($round your response to two decimal places$).$

D$)$ Number of days that would result in $99\%$ probability of completion $=\_\_\_$ days $($round your response to two decimal places$).$
