Answer: The SST for the data set is 8.
Step-by-step explanation:
Since we have given that
Coefficient of determination (R²) = 0.25
SSE for the data = 6
SST = ?
As we know the formula for coefficient of determination:

Hence, the SST for the data set is 8.
The length is (3/5 -1/5)=2/5
the height is also 2/5
area: length * height =2/5 *2/5=4/5
D is correct.
Answer: The answer is nine, because
The answer should be D.
