Calculate the expected duration and variances for each activity. Use the expected durations to Develop

a project network for this problem and answer the following questions. questions (Note: when using the

Z tables - round your Z values to two decimal places before getting the probabilities from the tables. DO

NOT round standard deviations prior to calculating Z values)

NOTE: Enter probabilities as decimals (i.e 92.31% should be entered as 0.9231)

a) How many weeks will it take to complete the project?

b) What activities are on the critical path?

c) What is the total variance of the project (i.e. the activities that are on the critical path)? (Enter

to two decimal places)

d)

What is the total standard deviation of the project (i.e. the activities that are on the critical

path)? (Enter to two decimal places)

e)

What is the probability that the project will be completed in less than 37 days? (Enter to three

decimal places)

f) What is the probability that the project will take more than 29 days? (Enter to three decimal

places)
