(C) In the formula for the arithmetic mean of grouped data,$\bar{x} = \frac{\Sigma f_{i} x_{i}}{\Sigma f_{i}}$:$\bar{x}$ represents the mean of the data.$f_{i}$ represents the frequency of the $i$th class.$x_{i}$ represents the class mark or the mid-value of the $i$th class interval,calculated as $\frac{	ext{Upper limit} + 	ext{Lower limit}}{2}$.Therefore,$x_{i}$ represents the mid-value of the $i$th class.

Class	$5-10$	$10-15$	$15-20$	$20-25$	$25-30$	$30-35$
Frequency	$11$	$20$	$35$	$20$	$8$	$6$

In the formula $\bar{x} = \frac{\Sigma f_{i} x_{i}}{\Sigma f_{i}}$,$x_{i}$ represents ..........
