# T- score used in the solution is for alpa, not divided by 2. Why

Please am confused with how to check the t-score table. The video shows that you divide the alpha by 2 e.g alpha is 0.05, divide by 2 which gives 0.025.

We are supposed to check 0.025 against the degree of freedom, to get the intersect.

But solution keeps using the alpha figure(without dividing it by 2).

Please I need clarification.

Hi,

Which solution?

in the exercise solution file, t-statistics for alpha (0.05/2) or (alpha 0.025) is correct -> 2.26.
