Combine the data from Exercises 19.5 and 19.6 into a two-way contingency table and run the appropriate test. How does the question that the two-way classification addresses differ from the questions addressed by Exercises 19.5 and 19.6?

Exercises 19.6

Following up the study referred to in Exercise 19.5, Hraba and Grant (1970) repeated the Clark and Clark study. The studies were not exactly equivalent, but they were close enough and the results are interesting. They found that out of 89 Black children, 28 chose the White doll and 61 chose the Black doll. Run the appropriate chi-square test on their data and interpret the results.

Exercise 19.5

In an old, but very important and influential, study by Clark and Clark (1939), Black children were shown Black dolls and White dolls and were asked to select one to play with. Out of 252 children, 169 chose the White doll and 83 chose the Black doll. What can we conclude about the behavior of these children.
