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
-A college professor classifies his students according to their grade point average (GPA) and their gender. The resulting cross-classification table is shown below. $$\begin{array}{l}\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\text { GPA }\\\begin{array} { | l | c c c | } \hline \text { Gender } & \text { Under 2.0 } & \text { 2.0 - 3. 0 } & \text { Over 3.0 } \\\hline \text { Male } & 10 & 30 & 15 \\\text { Female } & 15 & 25 & 35 \\\hline\end{array}\end{array}$$ If you made a pie chart for male GPAs and a pie chart for female GPAs, those pie charts would look the same.
