Answer:
A
Step-by-step explanation:
We can use a simple formula to solve for SST. The formula is:
[tex]SST=\frac{SSE}{1-R^2}[/tex]
Where
the coefficient of determination is [tex]R^2[/tex]
Now, we are given [tex]R^2[/tex] is 0.25 and SSE is 12 (not SEA, it's SSE). we simply put it into the formula and solve for SST:
[tex]\\SST=\frac{12}{1-0.25}\\SST =16[/tex]
correct answer choice is A
