Question
Use the calculator provided to solve the following problems. - Consider a \( t \) distribution with \( 13 \) degrees of freedom. Compute \( P(t \geq 1.66) \). Round your answer to at least three decimal places. - Consider a \( t \) distribution with \( 21 \) 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. The diagram includes a simple input interface with two empty fields: 1. \( P(t \geq 1.66) = \) [input box] 2. \( c = \) [input box] Below the input boxes are three icons: a calculator, a reset icon, and a help icon.

Expert Solution
Step 1

The degrees of freedom is 13.

Using the Excel formula “=T.DIST.RT(1.66,13)”, P(t ≥ 1.66) = 0.0604

The Excel output is given below:

Statistics homework question answer, step 1, image 1

Thus, P(t ≥ 1.66) = 0.0604
