For the following questions we are interested in a comparison of the 16 years education vs. > 16 years. (Recall we did the analysis on the log scale, so these are actual means on the log scale, so use the notation μlog1 . You do not have to back transform anything for this assignment).
1. For the comparison of 16 years education vs. > 16 years, write out the linear combination of means ( ) we are interested in and the estimator (g) Use all five groups in notation to explicitly show all work.
2. What are the coefficients of the linear combination in (1)? (i.e. What are the C's)
3. Obtain an estimate of the linear combination using the table of group averages (on the log scale).
