4.17 Refer to the previous exercise. Table 4.14 shows the fit of the model with only

E/I and T/F as predictors.

a. Find for someone of personality type introverted and feeling.

b. Report and interpret the estimated conditional odds ratio between E/I and

the response.

c. Use the limits reported to construct a 95% likelihood-ratio confidence

interval for the conditional odds ratio between E/I and the response.

Interpret.

d. The estimates shown use E for the first category of the E/I scale. Suppose

you instead use I for the first category. Then, report the estimated conditional

odds ratio and the 95% likelihood-ratio confidence interval. Interpret.

e. Showsteps of a test of whether E/I has an effect on the response, controlling

for T/F. Indicate whether your test is aWald or a likelihood-ratio test.
