(b)4 quantitative, 0 categorical

(c)5 quantitative, 1 categorical

(d)2 quantitative, 1 categorical

(e)2 quantitative, 2 categorical

The variables arc the topics that were investigated.

Variables=Age, Marital States and Earned income

Categorical/qualitative variables place the individuals into a category, while a quantitative variable is a numerical variable.

Age is a quantitative variable, since the age takes on numerical values (such as 24 years).

Marital status is a categorical variable, since the categories arc Single, Married, Divorced, Widowed, etc.

Earned, income is a quantitative variable, since the earned income takes on numerical values (such as 3000 dollars).

We then note that there are 2 quantitative variables (age and earned income) and 1 categorical variable (earned income).

Conclusion:

Option (d) 2 quantitative, 1 categorical is the number and type of variables recorded.
