9.3 For this exercise, you will open the SPSS sample file called workprog.sav and select two discrete variables and one continuous variable to build a histogram paneled on both columns and rows. For the x-axis use the variable labeled as Age in years and named “Age.” The discrete variable named “Marital” and labeled as Marital status will be the column-paneled variable. The row-paneled variable is named “Ed” and labeled as Level of education. Look at the finished graph, and answer the following questions:

(a) Which of the row panels (Level of Education) contains the most people?

(b) Which of the six groups had the most participants in the age interval 17.5 to 18.5 years, and how many are in that group?

(c) Which group had a distribution of ages that most closely resembled a normal distribution?

(d) What is the shape of the distribution for unmarried individuals with a high school degree?
