Question

Use Table C or software to find the following. (Round your answers to three decimal places.)

(a) the critical value for a one-sided test with level α = 0.025 based on the t(8) distribution

t* =

Answer 1

Given, level of significance α = 0.025

Degrees of freedom df=8

Type of tail: One-tailed

the critical value for a one-sided test with level α = 0.025 based on the t(8) distribution

t* =2.306

The Critical value table is

OR by using R command

round(qt(0.025,8,lower.tail=F),3)

 [1] 2.306
