Answer
An appropriate graphical summary for age is a stem and leaf plot, for income is a histogram, for marital status is a bar graph or pie chart, and for the number of vehicles is a histogram or dot plot.
Work Step by Step
The graphical summary for age is a stem and leaf plot, as it provides a clear visual summary of the data. Age is a continuous variable that can take different values, but the range is not large.
The graphical summary of income is a histogram as the values of income are continuous variables,which means it can take any values.The range of income is large enough.
The graphical summary of marital status is a bar graph or a pie chart as nominal or quantitative data is best described in it.
The graphical summary of the number of vehicles is a dot plot or a histogram, as it is a discrete variable. The histogram shows a clear summary of vehicles.
