Unit 6, Lesson 2
Relative Frequency Tables
Integrated Math 1
Practice
Problem 1
A teacher asks their students whether they studied for a quiz, then scores the quiz. A relative frequency table displays some of the information they collected.
| studied | did not study | |
|---|---|---|
| passed quiz | 86% | 14% |
| failed quiz | 46% | 54% |
What does the 86% represent?
Problem 2
The accessory choices of 143 people are recorded in the table.
| wearing a watch | no watch | |
|---|---|---|
| wearing a belt | 62 | 32 |
| no belt | 29 | 20 |
Create a relative frequency table that could be used to show the percentages of belt wearers who wear a watch or not as well as the percentages of people without belts who wear a watch or not.
