Project Estimation and PERT (Part 7): 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. You can even win cool PM Prep Flashcards and other prizes for doing well on the 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.
