Condition on age. Refer to the previous exercise. Find the conditional distribution of status for each of the four age categories. Display the distributions graphically and summarize their differences and similarities.
Full-time and part-time college students. The Census Bureau provides estimates of numbers of people in the United States classified in various ways.29 Let's look at college students. The following table gives us data to examine the relation between age and full-time or part-time status. The numbers in the table are expressed as thousands of U.S. college students.
(a) What is the U.S. Census Bureau estimate of the number of full-time college students aged 15 to 19?
(b) Give the joint distribution of age and status for this table.
(c) What is the marginal distribution of age? Display the results graphically.
(d) What is the marginal distribution of status? Display the results graphically.
