Using a class width of 25, develop a frequency distribution of the data starting with the following intervals:

- 25–49.9
- 50–74.9
- 75–99.9
- and so on.

Answer :

Final answer:

To develop a frequency distribution using a class width of 25, determine the midpoint and frequency for each interval. Use this information to analyze the data.

Explanation:

To develop a frequency distribution using a class width of 25, we start with the first interval 25-49.9. The midpoint for this interval is 37.45, and we graph it on the x-axis. Then, we determine the frequency for this interval. We repeat this process for each subsequent interval, using the given class widths and finding the midpoint and frequency for each interval.

For example, for the interval 50-74.9, the midpoint is 62.45 and the frequency is determined by the data values falling within this interval. We continue this process for all intervals until we have developed a complete frequency distribution.

Once we have the frequency distribution, we can use it to analyze the data and draw conclusions about its distribution and characteristics.
