Suppose that weekly expenses for two student organizations are thought to be similar. A random sample of 10 weeks yields the following weekly expenses for each organization:
Organization A Organization B
$ 119.25 $ 111.99
$ 123.71 $ 116.62
$ 121.32 $ 114.88
$ 121.72 $ 115.38
$ 122.34 $ 115.11
$ 122.42 $ 114.40
$ 120.14 $ 117.02
$ 123.63 $ 113.91
$ 122.19 $ 116.89
$ 122.44 $ 121.87
Use a Wilcoxon Rank Sum Test to determine whether expenses differ for the two organizations. Test at the 0.05 level.

A student is interested in the sleep quality of students. That
student selects a random sample of 21 students (age 19-24 years)
from each four undergraduate years (Freshman, Sophomore, Junior and
Senior), and applies Pittsburgh Sleep Quality Index (PSQI) and
obtains their responses. PSQI includes 19 self-reported items and
is designed to evaluate overall sleep quality (Data are presented
in Table 1 below). The student is interested in determining whether
there is any evidence of a difference in sleep quality...
