Analyze the data given under Study Suggestion 1 with a computer program for logistic regression. Using dummy coding for the categorical independent variable, assign 0 to the second category (labor leader). (a) What is the regression equation?

(b) What is -2LL (log likelihood) for a model consisting of an intercept only?

(c) What is -2LL for a model consisting of an intercept and X?

(d) What is the difference between the -2LL of (a) and (b)? How is it interpreted?

(e) Show how you would use the regression coefficient for X to estimate the odds ratio.

(f) Using the regression equation, estimate the probability of perceiving the message as unbiased when it is attributed to (1) a leading economist and (2) a labor leader.

(g) Transform the probabilities obtained under (f) into odds.
