Question

(1 point) Select the correct answer(s) from the choices below. A null hypotheses (HO) was rejected at significance level alpha 0.05. What will be your conclusion at alpha0.01 and 0.1? OA. Reject HO at alpha 0.01 but not at alpha-0.1. OB. Reject HO at alpha 0.01 and need more information to conclude about 0.1. C. Fail to reject HO at both alpha 0.1 and 0.01. D. Reject HO at alpha 0.1 but not at alpha -0.01. OE. Reject H0 at alpha 0.1 and need more information to conclude about 0.01. F. Reject HO at both alpha 0.1 and 0.01. G. None of the above

Explanation / Answer

Given that, a null hypothesis (H0) was rejected at significance level alpha = 0.05 .

That means, p-value of the given test is less than alpha = 0.05

Here, alpha = 0.05 is less than alpha= 0.1 but greater than alpha = 0.01

Therefore we can reject H0 at alpha=0.1 but we can not decide to reject or do not reject H0 at alpha =0.01. We need p-value to coclude at alpha = 0.01

Hence, we reject H0 at alpha = 0.1 and need more information to conclude about 0.01

Answer: E)
