7.3 Table 7.22 depicts data that was obtained from the 1994 administration of the GSS on whether the respondent was born in the United States, the respondent’s sex, and the respondent’s ability to use the Internet.

a. Fit the homogeneous association model to the data and examine its standardized residuals. Do any appear very large (far from 0)? Are many residuals very small (close to 0)?

b. Fit the complete independence model to the data and examine its standardized residuals. Do any appear very large (far from 0)? Are many residuals very small (close to 0)?

c. Test whether there is a significant difference in fit between the homogeneous association and complete independence models and report the results of the test.

d. Explain which of the two models (homogeneous association or complete independence) you would choose based on the residuals and fit statistics.
