Use the ALEKS calculator to solve the following problems.

(a) Consider a t distribution with 13 degrees of freedom. Compute \( P(-1.39 < t < 1.39) \). Round your answer to at least three decimal places.

\[ P(-1.39 < t < 1.39) = \Box \]

(b) Consider a t distribution with 18 degrees of freedom. Find the value of \( c \) such that \( P(t \leq c) = 0.05 \). Round your answer to at least three decimal places.

\[ c = \Box \]
