Question

When the length of critical path of a project is 40 days and the variance of the project is 4 days, what due date should be set for this project so that the probability of completing the project is 95%? Since it is on days, round the answer to the nearest higher integer. The z value of 95% is 1.645. ____?

Answer 1

44

Step-by-step explanation:

Calculation for the due date that should be set for this project

First step is Find the square root of 4 which is 2 then we are going to cross multiply 2 by z value of 95% which is 1.645 which gives us 3.29(2×1.645).

Second step is to add the numbers of days which is 40 days to 3.29 which gives us the due date that should be set for this project which is 43.29(40 days + 3.29) approximately 44.

Due date=

1.645 = (x - 40)/√4

1.645=(x - 40) /2

Cross multiplication

1.645×2=(x-40)

x=(1.645×2)+40 days

x=3.29+40 days

x=43.29

Approximately 44 days

Therefore the due date that should be set for this project will be 44 days
