Question

A hypothesis test with a sample of n = 15 participants produces a t statistic of t = +2.72. Assuming a one-tailed test with the critical region in the right-hand tail, what is the correct decision?

Select one:

The researcher can reject the null hypothesis with α = .05 but not with α = .01.

The researcher must fail to reject the null hypothesis with either α = .05 or α = .01.

The researcher can reject the null hypothesis with either α = .05 or α = .01.

It is impossible to make a decision about H₀ without more information.
