Internet Classes
A survey of 25 students was conducted to determine how they rate the quality of Internet classes. Students were asked to rate the overall quality from 0 (no quality at all) to 100 (extremely good quality). The stem-and-leaf display of the data is shown below. $$\begin{array} { c | l } \text { Stem } & \text { Leaves } \\\hline 3 & 15 \\4 & 01457889 \\5 & 0134677 \\6 & 24568 \\7 & 29 \\8 & \\9 & 5\end{array}$$ NARREND
-If two nominal variables are unrelated, the patterns exhibited in their corresponding bar charts should be approximately the same. If a relationship exists, then some bar charts will differ from others.
