8.3 You must visually display the relationship between two categorical variables using the population pyramid graphing method. The variables you use are found in the SPSS sample file called workprog.sav. The variable “prog” (program status) is the split variable, and “ed” (level of education) is the distribution variable. Build the population pyramid to compare these discrete variables split into two groups of program status, 0 and 1. It has been determined that the categories of 0 and 1 are approximately equal; therefore, these distributions can be directly compared. Also, look at the finished graph, and answer the following questions:

(a) By looking at the graph, does it appear that program status and level of education are related?

(b) Which of the six categories contains the most observations?

(c) Which category has the least number of observations?
