Question: A sample of n = 25 scores produces a t statistic of t = -2.05. If the researcher is using a two-tailed test with a = .05, the correct statistical decision is:

answers

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

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

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

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