Use the following table to answer the questions. Calculated expected days for each task (round nearest whole). Task Description Pred. Optimistic Days Likely Days Pessimistic Days A Design snowman 5 B Coordinate volunteers 4 6 10 Collect decorations A,B 8 10 20 D Make snow B 9 11 20 F Build snowman D 14 16 30 F Decorate C.E 2 4 8 G Ceremony 1 1 1 Project duration = days Critical path is (letters only) Burst task is (letter only) Slack for task C = days Early finish of task Fis days It makes sense for tasks D and E to be laddered. How many days would the combined duration for these 2 tasks be REDUCED by if each could be divided into 2 equal subtasks? Calculate task variances (nearest 2 decimals) to determine the project standard deviation. Project standard deviation (nearest 2 decimals) = If you want to be 87% confident the project will be completed on time, how many days (nearest whole) must be ADDED to the duration? days If you want to be 93% confident the project will be completed on time, how many days (nearest whole) must be ADDED to the duration
