Use Cutpoint Grouping to Organize These Data into a Frequency

Use cutpoint grouping to organize these data into a frequency distribution.
-Lori asked 24 students how many hours they had spent doing homework during the previous week. The results are shown below. $\begin{array} { r r r r r r r r r r r r } 11 & 10 & 11 & 9 & 11 & 11 & 14 & 12 & 11 & 8 & 12 & 10 \\ 10 & 12 & 11 & 10 & 12 & 11 & 10 & 12 & 10 & 12 & 12 & 9 \end{array}$ Construct a frequency distribution. Use 4 classes, a class width of 2 hours, and a lower limit of 8 for the first class. $\begin{array}{l|l} \text { Hours } & \text { Frequency } \\ \hline & \\ & \end{array}$
