Probabilities from a t-distribution
Problem
\(T ~ t_4\) . Use table or software (Eviews, Excel, Wolfram aplha, calculator,...) to find
- \(P\left( T>2 \right)\)
- \(P\left( \left| T \right|>2 \right)\)
- \(t\) such that \(P\left( T>t \right)=0.05\)
- \(t\) such that \(P\left( \left| T \right|>t \right)=0.05\)
- I you solved e) using software, solve it using a table (and vice versa)
