Accepted Answer

To construct a pie or bar chart for each variable in the table, we would first create a pie chart for the variable "Sex" to show the distribution of male and female cases. We would then create a bar chart for the variable "Support for capital punishment" to display the frequency of approval and disapproval. Next, we would create a bar chart for the variable "Level of Education" to illustrate the distribution of individuals with different education levels. Finally, we would create a bar chart for the variable "Age" to display the age distribution of the cases. Each chart would provide a visual representation of the data, allowing for easy comparison and analysis.
