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:
a.
The researcher can reject the null hypothesis with α = .05 but not with α = .01.
b.
The researcher must fail to reject the null hypothesis with either α = .05 or α = .01.
c.
The researcher can reject the null hypothesis with either α = .05 or α = .01.
d.
It is impossible to make a decision about H0 without more information.
