Given:

The table shows the number of hours of television watched by 129 students per week.

To construct and label a frequency histogram of the data:

Step-by-step explanation:

Since the given class intervals are in the discontinuous form.

In a histogram, the bars should be continuously placed without any gap. Hence we should make the class intervals continuous.

So, let us find the adjustment factor.


\begin{gathered} Adjustment\text{ }Factor=(1)/(2)\lbrack lower\text{ }limit\text{ of the class interval}-\text{upper limit of the preceding class interval\rbrack} \\ =(1)/(2)\lbrack2-1\rbrack \\ =(1)/(2) \\ =0.5 \end{gathered}

So, the table becomes,

The histogram graph is,
