1. ## t- distribution comfusion

I'm asked to find the P (T < ?? ) , v= 26 , α = 0.005

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 ? https://imgur.com/a/PuPgT

You have to take into account that this table shows positive values of the T distribution. P(T<-2.779)=P(T>2.779) because the T distribution is symmetric. I hope this helps.
