You are examining problems that have surfaced, constraints experienced, and non-value-added activities identified during process execution. You are analyzing a sample of readings from the processes. If you need to decrease your confidence interval for your measurements, what should you do regarding the sample size you have selected? A. You should increase the sample size to decrease the confidence interval B. You should decrease the sample size to decrease the confidence interval C. You should keep the same sample size since it does not have any effect on the confidence interval D. You should keep the same sample size but decrease the number of measurements in the sample Hint: Confidence interval is the range of statistical values within which a result is expected to fall with a specific probability.

We also offer 110 free questions at www.free-pm-exam-questions.com . We are a PMI Registered Education Provider. Answer and Explanation: The Correct Answer is A. Confidence interval is the range of statistical values within which a result is expected to fall with a specific probability. A confidence interval (CI) is a particular kind of interval estimate of a population parameter. Instead of estimating the parameter by a single value, an interval likely to include the parameter is given. In this way, confidence intervals are used to indicate the reliability of an estimate. The smaller the confidence interval, the more accurate the measurement is. Therefore, if we want to decrease the confidence interval, i.e. we want a closer estimate, we need to increase the sample size. Your e-mail address will never be displayed on the site.

 Maitra Visitor Some of your questions are very hard, like this confidence interval. I only prepared by reading PMBOK and Rita and finding it really hard, not getting more than 65% on your free exams. Is it too early to sit for actual exam? What should be the target score in the 3 free exams? Your e-mail address will never be displayed on the site. Check this box to be notified of replies to this topic.

 Cornelius Fichtner Offline Administrator PrepCast Instructor Posts: 1180 Karma: 38 Thank you received: 204 Maitra, The PMP Exam is a very "wide" exam. Meaning that you must expect to see questions on the exam on PM related topics that you may never have heard of before. That's what makes it so difficult. Generally speaking, we say that you should score 80% in your mock exams before you are ready. (That is 80% THE FIRST TIME that you take an exam -- not the second or third time that you repeat the same exam). This article here has some further tips in that regard: www.project-management-prepcast.com/free...passing-the-pmp-exam Your e-mail address will never be displayed on the site.
