A sample of 200 high school students were asked how many hours per week they spend watching television. The following frequency distribution presents the results. $$\begin{array} { c c }
\hline { \text { Time Spent Watehing Television } } \
\hline \text { Number of hours } & \text { Frequency } \
\hline 0.0 - 3.9 & 38 \
4.0 - 7.9 & 38 \
8.0 - 11.9 & 34 \
12.0 - 15.9 & 23 \
16.0 - 19.9 & 24 \
20.0 - 23.9 & 23 \
24.0 - 27.9 & 20 \
\hline
\end{array}$$ Construct a frequency ogive for the frequency distribution.

To construct the ogive, we need to find the cumulative frequency for each class interval. Starting with the first class interval, we have a frequency of 38. The cumulative frequency for this interval is also 38. For the second interval, we add the frequency of 38 to the cumulative frequency of the first interval, giving us a cumulative frequency of 76. We continue this process for all intervals, resulting in the cumulative frequency distribution shown in choice C. A cumulative frequency graph (ogive) is then constructed by plotting the upper limits of the class intervals on the x-axis and the corresponding cumulative frequencies on the y-axis.
