  PMP Quiz Contest - Activity Duration Estimates

Activity Duration Estimate Free Sample Questions for PMP Certification Project Estimation and PERT (Part 8): The expected duration of your project is 48 days and standard deviation is 4 days. Your management wants to know the project duration estimate with a 95% confidence level. What estimate would you give them? I’m not going to answer this question just yet. In fact, I’m going to challenge you to solve it. We have gone through the theory and now is the time for some exam practice. Today we are going to try something new - sample questions - which we haven’t done before on this site. Yes, sample questions in the form of a quiz.

I researched a lot of online quiz services and finally settled on Google Forms, primarily because of 2 reasons - it has the least restrictions and is (of course) free. Google Forms is more suited for surveys, and not quizzes. But I’ve modified the survey to emulate a quiz program with a self-grading feature. If you like my first attempt at quizzes, and want me to do more of it, let me know.

  1. Since confidence level is 95% its 2 sigma
    so if estimate should be 48
    P=50,O=46

  2. Hi Preetham,

    Thanks for your comment. I'm not sure whether you are asking a question or making a statement.

    Either way, I'll reserve my comments for now and let other readers respond to your comments. Feel free to discuss the questions here. I'll be a silent observer.

    I'll see how participants score on the exam over the next few days. If the scores are not moving up, I'll consider posting some hints.

    After the contest ends, I'll post detailed explanations and also address the comments posted here.

    Good luck :)

  6. Hi Prashant,

    The page looks fine on my screen and people are taking the quiz almost everyday. I suspect that it's a problem with your browser blocking out iframes. Send me some screenshots at harwinder at deepfriedbrainpmp dot com so that I can help troubleshoot the problem.

    For the answers, look at point 2 under the "Contest Result" section above.

    BR.
