The correct option is (d) 2 quantitative, 1 categorical

Step by step solution

Given information

You keep track of the age, marital status, and earnings of 1463 women.

Concept

Qualitative variables are indicated individual variables whereas quantitative categories are indicated numerical variables.

Explanation

The variables represent the topics that were looked into.

Variables=Age, Marital Status, and Earned income

Individuals are placed into categories by categorical/qualitative criteria, whereas quantitative variables are numerical quantities. Because age has numerical values, it is a quantitative variable (such as 24 years). Because the categories are Single, Married, Divorced, Widowed, and so on, marital status is a categorical variable. Because earned money takes on numerical values, it is a quantitative variable (such as 3000 dollars). Then we notice that there are two quantitative variables (age and earnings) and one categorical variable (gender) (earned income). Therefore the correct option is (d) 2 quantitative, 1 categorical.
