Use the ALEKS calculator to solve the following problems.

(a) Consider a \( t \) distribution with \(13\) degrees of freedom. Compute \( P ( t \leq - 1.2 )\). Round your answer to at least three decimal places.

\(P ( t \leq- 1.2)= \)

(b) Consider a \( t \) distribution with \(20\) degrees of freedom. Find the value of \(c\) such that \( P ( - c < t < c ) = 0.95 . \) Round your answer to at least three decimal places.

\( c = \square\) 

Answer

(a) \(P(t \le - 1.2) = 0.1258 \approx 0.126\)

 

(b) \(c= 1.725\)
