The sample is the incomes of home owners in Texas with mortgages.
Work Step by Step
The population represents all the possible measurements in a particular study which in this case is the incomes of all the home owners in Texas. A sample is a subset of a population. The incomes of home owners in Texas with mortgages would in this case be the sample because it represents a portion of the total population. By observing the Venn diagram, you can identify the population as the whole and the sample as a part of the whole. The Rectangle in the diagram is the whole and the circle is included as part of that whole. The circle represents the sample and the rectangle represents the population.
