firm would like to monitor the progress of new agents. The goal is to identify? "superstar agents" and keep them with the company. The firm has been monitoring sales of new agents over the past two years. The response of interest is the profit to the firm? (in dollars) or contracts sold by agents over their first year. Among the possible predictors of this performance is the number of new accounts developed by the agent during the first three months of work. Some of these agents were located in new? offices, whereas others joined an existing office. Complete parts? (a) through? (e) below.

(c) Assuming that the model meets the conditions for the? MRM, use the incremental? F-test to assess the size of the change in

R2.

?(The value of

kfull

for the model with dummy and interaction is? 3, with 2 slopes added. You will need to fit the simple regression to get its

R2

for comparison to the multiple? regression.) The critical value for the incremental? F-test is 4. Calculate the? F-statistic.
