Expert Solution
a)
b)
| predicted val=29.388+20*-0.96= | 10.2 crimes | |
c)
| SST=Syy= | 290.8750 | |
| SSE =Syy-(Sxy)2/Sxx= | 68.481 | |
| SSR =(Sxy)2/Sxx = | 222.3936 | |
| s2 =SSE/(n-2)= | 11.4136 | |
| std error σ = | =se =√s2= | 3.3784 |
d)
| Coeffficient of determination R^2 =SSR/SST= | 0.7646 | ||
this tells us that 76.46 % variation in # of crimes can be explained by this model
