Question

a group of 250 middle school students were asked whether they prefer playing video games or watching tv in their spare time. the genders of the students and their responses are reported in the following table.
(a) what percentage of the students prefer watching tv?
(b) what percentage of the students are girls?

Explanation:

Step1: Calculate total number of students preferring watching TV

Total students preferring watching TV = \(53 + 92=145\)
Total number of students = \(67 + 38+53 + 92 = 250\)
Percentage of students preferring watching TV (a) = \(\frac{145}{250}\times100\)
