Step 1/1

17) SSE can never be

The correct answer is:

a. larger than SST

Explanation:

Since SSE represents only the unexplained variation, it can never be larger than SST, which represents the total variation in the data. SSE can be equal to or smaller than SST depending on the goodness of fit of the model. SSE will be equal to SST if the model perfectly fits the data (i.e., all the variability in the data is explained by the model), and SSE will be smaller than SST if the model provides a good fit to the data (i.e., explains a significant portion of the variability in the data).

Final Answer

the final answer is:

17) option a

18) option a

19) slope = 2.5435

20) intercept = 12.1965
