Chapter 4 Problems Problem 5 The distribution is be-modal with peaks at 1 and at 7 days. It is skewed to the right with a fairly long tail and some outliers. However, the peak at 1 day is probably due to incorrect diagnoses. Some of those events would extend into 2 day stays. If those are removed, then there is a unimodal distribution with a peak at 7 days, a median at about 8 day, and an IQR of about 6 days. Problem 6 This distribution is unimodal, with the mode near 1. The distribution is skewed to the right with one outlier far to the right. Most students sent five or fewer e-mails.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
