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$).$
