**Educational Website Content: Constructing a Frequency Distribution Table** **Example Data:** The data represent the time, in minutes, spent reading a political blog in a day. Here are the recorded times: 26, 31, 19, 16, 42, 49, 30, 40, 31, 43, 9, 18, 3, 41, 34, 11, 13, 12, 0, 33 **Objective:** Construct a frequency distribution using 5 classes. Include the midpoints, relative frequencies, and cumulative frequencies. ---- **Instructions to Complete the Table:** 1. **Class Intervals:** - Determine the range: Highest value (49) - Lowest value (0) = 49. - Number of classes: 5. - Class width: \(\lceil 49 / 5 \rceil = 10\). 2. **Filling in the Classes:** - First class: \(0 - 9\) - Second class: \(10 - 19\) - Third class: \(20 - 29\) - Fourth class: \(30 - 39\) - Fifth class: \(40 - 49\) 3. **Frequency:** - Count how many data points fall within each interval. 4. **Midpoints:** - Midpoint for each class is calculated as \((\text{lower limit} + \text{upper limit}) / 2\). 5. **Relative Frequency:** - Relative frequency is calculated as \(\text{class frequency} / \text{total number of data points}\). 6. **Cumulative Frequency:** - Add frequencies cumulatively from the first class to the last class. --- **Interactive Table:** | Class | Frequency | Midpoint | Relative Frequency | Cumulative Frequency | |-----------|-----------|----------|--------------------|----------------------| | 0 - 9 | | | | | | 10 - 19 | | | | | | 20 - 29 | | | | | | 30 - 39 | | | | | | 40 - 49 | | | | | **Exercises:** - Identify the class with the greatest
