Researchers are looking to compare two different drug interventions. The patient's addiction scores for the two different interventions group are shown as the following table. Column 3 represents the susceptibility measures for patients in group 1. (Assume data from all the three columns are normally distributed).

Score Group 1	Score Group 2	Susceptibility Group1
5	4	3.56
3	3	2.23
1	4	-4.93
2	5	-4.97
3	4	-1.92
7	1	2.85
6	6	-1.98
5	3	4.35
2	7	-0.44
4	6	-2.48

Another factor that may potentially influence the measurement for group 1 is patient susceptibility. Suppose we know the linear relationship is:

score= 4.197 - 0.275 * susceptibility

Please interpret the slope. What is the predicted sore if susceptibility is 2?
