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
