**Transcription for Educational Website** **Question 22** Approximate the median for the following GFDT. (Report the answer as the midpoint of the class containing the median.) | Data | Frequency | |-------|-----------| | 40 - 44 | 1 | | 45 - 49 | 1 | | 50 - 54 | 3 | | 55 - 59 | 6 | | 60 - 64 | 8 | | 65 - 69 | 12 | | 70 - 74 | 10 | | 75 - 79 | 22 | | 80 - 84 | 12 | **Input Box:** median = [ ] **Button:** Submit Question **Explanation:** The table is a grouped frequency distribution table (GFDT) showing data categories and their respective frequencies. Each 'Data' range represents a class interval, and the 'Frequency' column shows how many observations fall within each interval. The task is to find the median class and report the midpoint of that class as the median.
