A research group surveyed 198 parents and 200 children and recorded their responses to the question, "How much free time does your child have?" or "How much free time do you have?" The responses are shown in the table below:

a. Define the sample and the population of interest to the researchers.
b. Describe the variables that have been measured in this survey. Are the variables qualitative or quantitative? Are the data univariate or bivariate?
c. What do the entries in the cells represent?
d. Use comparative pie charts to compare the responses for parents and children.
e. What other graphical techniques could be used to describe the data? Would any of these techniques be more informative than the pie charts constructed in part d?
