When taking this exam, I will respect the honor code for this course. I will display academic integrity by not using unauthorized devices, unauthorized websites, unauthorized notes, unauthorized formula sheets, etc. I will refrain from discussing the exam and its questions with my peers, even after the course has ended.   I will NOT use a statistical calculator with built-in distributions, the internet, or excel to compute values for the various probability distributions on this test. I will either plug values into a formula from my provided formula sheet, use the normal table provided for this course, or use the t-table provided for this course to obtain these probabilities instead. I will not take images of this exam for my personal use or for others’ to use. Nor will I ask for assistance in solving any of these questions.   The work on this exam is a reflection of what I personally am able to do at this specific moment in time.
