Given that we have significant evidence to reject null hypothesis with a=10%. Another elements keep the same, what conclusion if we change the a to 5%?

A, still reject B fail to reject C not enough information

Solution

Ans: C (Not enough information)

We will be rejecting the null hypothesis when the corresponding observed significance (P-value) is less than 0.1.

but we do not have the information that P-value is above 5% or below 5%.

If the exact P-value is known only, we can conclude basing on 5% significance level.
