1. The problem statement, all variables and given/known data I'm asked to find the P (T < ?? ) , v= 26 , α = 0.005 2. Relevant equations 3. The attempt at a solution From the table , we could notice that P (T > 2.779) , v= 26 , α = 0.005 , So , i think the ans should be P (T < -2.779 ) , v= 26 , α = 0.005 , But the ans is P (T < 2.779) , why ? Is the ans wrong ?
