A construction project has four separate components that must be completed in order. The expected values and standard deviations of the completion times of the activities are listed below. Assuming that the four activities are independent, determine the expected value and standard deviation of the completion time of the project. Activity Expected Completion Time (Days) std. Dev.
1 17 6
2 12 3
3 26 4
4 7 2

Expected value of completion time of project =
Standard deviation of completion time of project =
