Question
A sample of 150 individuals (males and females) was surveyed, and the individuals were asked to indicate their yearly incomes. Their incomes were categorized as follows.Category 1 $20,000 up to $40,000
Category 2 $40,000 up to $60,000
Category 3 $60,000 up to $80,000
The results of the survey are shown below.
| Income Category | Male | Female |
| Category 1 | 10 | 30 |
| Category 2 | 35 | 15 |
| Category 3 | 15 | 45 |
