Question

What is the absolute value of the critical value for a two-tailed, independent-samples t test when the total sample size is 26 and the alpha level (or p-level) is 0.01 (1%)?

Answer 1

The critical value for a two tailed test

t₍₂₅,₀.₀₁₎ = 2.4851

Explanation:

Explanation:-

Given sample size 'n' = 26

The level of significance '∝' = 0.01

degrees of freedom = n-1 = 26-1 =25

we will use 't' - distribution

`t = (x^(-) -mean)/((S.D)/(√(n) ) )`

The critical value for a two tailed test

t₍₂₅,₀.₀₁₎ = 2.4851
