A hypothesis test with a sample of n = 25 participants produces a t statistic of t = +2.53. Assuming a one-tailed test with the critical region in the right-hand tail, what is the correct decision?​(A) The researcher can reject the null hypothesis with a = .05 but not with a = .01.(B) The researcher can reject the null hypothesis with either a = .05 or a = .01.(C) The researcher must fail to reject the null hypothesis with either a = .05 or a = .01.(D) It is impossible to make a decision about H0 without more information.

Answer:

Option B is right.

Step-by-step explanation:

Given that a hypothesis test with a sample of n = 25 participants produces a t statistic of t = +2.53.

df = 24

p value = 0.009191

Since p value is less than 0.01 , we reject null hypothesis at 1%, 5% and 10% significance level.

(B) The researcher can reject the null hypothesis with either a = .05 or a = .01
