Aproject being analyzed by pert has 38 activities, 16 of which are on the critical path. if the estimated time along the critical path is 90 days with a project variance of 25, what is the probability that the project will be completed in 88 days or less?

required probability is .3446

Step-by-step explanation:

It is given that most expected time of completion = 90 days

Variance = 25

We know that

Thus the standard normal deviate is given by

Applying values we get

Using the standard table for Z we have probability corresponding to Z = -0.4 equals 0.3446

Thus required probability is .3446

answer: about 22.67

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
