Below are SAS results from a hypothetical data set using the following variables:

WAGE Outcome variable ranging from $2/hour to $15/hour EDUC Education level ranging from 8 to 13 UNION Dummy variable (1 = in a union job; 0 = not in a union job)

JOBCLUB Dummy variable (1 = got job from job club; 0 = didn’t get job from job club)

a) Write the prediction equation based on this model.

b) Interpret the point estimate for the jobclub variable.

c) Interpret the point estimate for the union variable.

d) Calculate and interpret the confi dence interval for the jobclub variable.

e) Calculate and interpret the confi dence interval for the union variable.
