Question

A researcher obtains t = 2.01 for a repeated-measures study using a sample of n = 30 participants. Based on this t value, what is the correct decision for a two-tailed test?

• A. Fail to reject the null hypothesis with either α = .05 or α = .01

• B. Reject the null hypothesis with α = .05 but fail to reject with α = .01

• C. Fail to reject the null hypothesis with α = .05 but reject with α = .01

• D. Reject the null hypothesis with either α = .05 or α = .01.

Answer 1

It is a two tailed test

t = 2.01

n = 30

df = n-1=29

By using t-distribution table, we get

P-value = 0.0538

Faile to reject the null hypothesis with either  = 0.05 or 0.01, since P- value is higher than the .

Option A is the correct one
