The degrees of freedom would be (n-1)=7. Your tabled t value for alpha =.05
with 7 degrees of freedom is 2.365. You will therefore reject Ho if your
t > 2.365 or t < -2.365.
If your t value came out to be -2.97, that means it is in the rejection region
and you would therefore reject Ho.
Rationale: It depends on how you define your rejection and acception region.
