To determine

Display the following data in histogram:

Length of Time Spent Reading
Time (min)	Tally	Frequency
$0-14$	$\left|\right|\left|\right|\cancel{|}\left|\right|\left|\right|\cancel{|}\left|\right|$	$12$
$15-29$	$\left|\right|\left|\right|\cancel{|}\left|\right||$	$7$
$30-44$	$\left|\right|\left|\right||$	$4$

Answer to Problem 8PT

  

Explanation of Solution

Given:

Length of Time Spent Reading
Time (min)	Tally	Frequency
$0-14$	$\left|\right|\left|\right|\cancel{|}\left|\right|\left|\right|\cancel{|}\left|\right|$	$12$
$15-29$	$\left|\right|\left|\right|\cancel{|}\left|\right||$	$7$
$30-44$	$\left|\right|\left|\right||$	$4$
$45-59$	$\left|\right|$	$2$

Concept Used:

With the bars of the different heights, data is shown with the graphical display is known as histogram. How many falls into the each range is represented by the each bar of the histogram.

Along the horizontal and vertical axis of the histogram, the independent and dependent variables are respectively plotted.

Calculation:

  

Conclusion:

Hence, the histogram is drawn as above.
