  • Consider a t distribution with

    5

    degrees of freedom. Find the value of

    . Round your answer to at least three decimal

Homework Answers

Answer #1

1) Given that, degrees of freedom = 8

P(t >= - 1.87) = P(t <= 1.87) = 0.9508

=> P(t >= -1.87) = 0.9508

2) Given that, degrees of freedom = 5

We want to find, c such that, P(-c < t < c) = 0.90

P(-c < t < c) = 0.9

=> 2 * P(t < c) - 1 = 0.90

=> 2 * P(t < c) = 1.90

=> P(t < c) = 0.95

Uisng TI-84 calculator we get, c = 2.015

=> P(-2.015 < t < 2.015) = 0.90
