Question

the two - way frequency table shows the number of students who participate in school sports or clubs at monroe high school. a. construct a relative frequency table by converting the data in the table to percentages. round to the nearest tenth if necessary. b. find the joint relative frequency of a sophomore who participates in school sports or clubs. c. what percentage of freshmen do not participate in school sports or clubs? d. what percentage of seniors participate in school sports or clubs?

Explanation:

Step1: Recall joint - relative frequency formula

Joint relative frequency = $\frac{\text{Frequency of the cell}}{\text{Total frequency of the table}}$

Step2: Identify relevant frequencies for sophomores in sports or clubs

The frequency of sophomores in sports or clubs is 60, and the total number of students is 480.

Step3: Calculate joint - relative frequency for sophomores in sports or clubs

Joint relative frequency = $\frac{60}{480}= 0.125$ or 12.5%

Answer:

12.5%
