### Frequency Distribution and Analysis of Text Messages Sent by a Class in an HourThe following frequency distribution represents the number of texts sent in an hour by a class. Utilize the table to answer the subsequent questions.#### Frequency Distribution Table| # of TEXTS | Frequency (f) ||------------|---------------|| 0 - 5 | 12 || 6 - 11 | 18 || 12 - 17 | 9 || 18 - 23 | 4 || 24 - 29 | 3 |#### Questions:1. **The class width is:** - (Provide the class width based on the table.)2. **The Σf is equal to:** - (Sum the frequencies to provide the total number of observations.)3. **The relative frequency for the class 12 - 17 is:** - (Express as a percent rounded to 2 decimals, calculate the relative frequency for the class interval 12-17.)---**Instructions for Analysis:**1. **Determining the Class Width:** - The class width is calculated as the difference between the upper limit of one class and the upper limit of the previous class. For example, the class width here can be determined from the intervals provided.2. **Calculating Σf:** - Σf represents the total number of observations and is found by summing the frequencies of all classes.3. **Calculating Relative Frequency:** - Relative frequency for a class is calculated as (Frequency of the class / Total frequency) × 100. Round off the result to 2 decimal places for the class interval 12-17.By completing this analysis, students will understand how to interpret frequency distributions and calculate class widths, total frequencies, and relative frequencies within a dataset.
