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

Answer:

The critical value for a two tailed test

t₍₂₅,₀.₀₁₎ = 2.4851

Step-by-step 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

                                          $t = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

The critical value for a two tailed test

t₍₂₅,₀.₀₁₎ = 2.4851
