Answer:
The sum of squares due to regression(SSR)=928.02
Step-by-step explanation:
We are given that
Dependent variable=y
Independent variable=x
n=10
SSE=505.98
We have to find the sum of squares due to regression.
It means we have to find SSR.
SST=
Hence, the sum of squares due to regression(SSR)=928.02
