Will students wait times for the arrival of an instructor who is a full professor differ
from the wait times for an instructor who is a graduate student? This question was
investigated by counting how many minutes undergraduate students waiting in two
small seminar classes, one taught by a full professor and one taught by a graduate
student. Suppose we want to examine if the time waited is different for the full
professor than for the graduate student.
a. Propose a parametric approach to answer this question. Mention clearly all
assumptions for such an approach.
b. Compare your approach in part a. to a bootstrap approach for a two-sample
problem. Clearly state your conlusions in relation to this problem.
