Construct a histogram for following frequency distribution :

Class-intervals Frequency
0-4 5
5-9 8
10-14 12
15-19 9
20-24 4

Put your values on the abscissa (x-axis) and the frequencies on the ordinate (y-axis). Use vertical bars to indicate frequency in each class interval.

To construct a histogram for this frequency distribution, follow these steps:

1. Determine the range of the data: The range is the difference between the largest value and the smallest value in the dataset. In this case, the smallest value is 0 and the largest value is 24, so the range is 24 - 0 = 24.

2. Determine the number of class intervals or bins for the histogram: To determine the number of bins, you can use a general guideline such as the square root of the number of observations or Sturges' formula. In this case, we have 5 class intervals already provided, so we will use those.

3. Determine the width of each class interval: The width of each class interval can be calculated by dividing the range by the number of class intervals. In this case, the range is 24 and there are 5 class intervals, so the width is 24 / 5 = 4.8. Since we cannot have decimal values for the width, we can round it up to 5.

4. Draw a horizontal axis and label it with the class intervals: The horizontal axis represents the range of values in the dataset. In this case, the class intervals are already provided, so you can label the axis as follows: 0-4, 5-9, 10-14, 15-19, 20-24.

5. Draw a vertical axis and label it with the frequency: The vertical axis represents the frequency or the number of observations that fall within each class interval. In this case, the frequency is provided in the frequency column of the data given.

6. Draw rectangles or bars above each class interval: The height of each bar represents the frequency of the corresponding class interval. The width of the bar corresponds to the width of the class interval. In this case, for the first class interval (0-4) with a frequency of 5, draw a bar with a height of 5 above the range 0-4. Repeat this for all the class intervals.

7. Add labels and title to the histogram: Finally, add a title to the histogram, such as "Frequency Distribution Histogram," and label the horizontal and vertical axes accordingly.

Once you follow these steps, you will have constructed a histogram for the given frequency distribution.
