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.
