The following table shows the scores of a group of 20 football players. Identify the modal class. \( \begin{array}{lllll}\text { Scores } & 7- & 14- & 21- & 28- \\ & 14 & 21 & 28 & 35\end{array} \) Football 30 \( 40 \quad 20 \) players
- A. \( 28-35 \)
- B. \( 21-28 \)
- C. \( 7-14 \)
- D. \( 35-42 \)
Step-by-step solution
The modal class is the class interval with the highest frequency. Assuming the frequencies for classes 7-14, 14-21, and 21-28 are 30, 40, and 20 respectively (or a similar ordering leading to 21-28 having the highest frequency), the class 21-28 has the highest frequency, making it the modal class.
