Here's the transcription of the given image for an Educational website:---### Problem Statement:#### (a) Consider a \( t \) distribution with 5 degrees of freedom. Compute \( P(-1.88 < t < 1.88) \). Round your answer to at least three decimal places.\[ P(-1.88 < t < 1.88) = \boxed{ } \]#### (b) Consider a \( t \) distribution with 5 degrees of freedom. Find the value of \( c \) such that \( P(t \geq c) = 0.10 \). Round your answer to at least three decimal places.\[ c = \boxed{ } \]---Explanation for potential graphs or diagrams:1. **\( t \)-Distribution Curve**: For part (a), one may include a bell-shaped t-distribution curve highlighting the area between \( -1.88 \) and \( 1.88 \).2. **Significance Level**: For part (b), a similar t-distribution curve can show the tail area (right-tail) corresponding to a probability of 0.10, indicating the critical value \( c \).
