The project manager of Good Public Relations gathered the data shown in the following table for a new advertising campaign Ell Click the icon to view the table a. How long is the project likely to take? (Make sure to round all intermediate cakculations fort to two decimal places.) The project is expected to take 36 weeks. (Enter your response rounded to two decimai places.) b. What is the probability that the project will take more than 37 weeks? Refer to the standard normal table. The probability is 0.2891. (Enter your response rounded to four decimal places.) c. Consider the path A-E-G-H-J. What is the probability that this path will exceed the expected project duration? Refer to the standard normal table The probability is (Enter your response rounded to four decimal places.)

Explanation / Answer

variance=

((b-a)/6)^2

Variance of AEGHJ

3.61

Cycle time of AEGHJ is 33.33

Probability of t>36 (As calculated by you)

z=(specified time-path expected time)/variance

1.405

Probaility

8.00%

1-NORMSDIST(-1.405)

Hence net probability is 8%
