Question

Recall that a test is statistically significant at a particular significance level if the null hypothesis is rejected. If a test is statistically significant at 5% level of significance, then

we cannot determine if the null hypothesis would be rejected at any other level of significance.
the null hypothesis will also be rejected at 1% level of significance.
the null hypothesis will not be rejected at 10% level of significance
the null hypothesis will also be rejected at 10% level of significance
the null hypothesis will not be rejected at 1% level of significance.

Answer 1

Option c.

Explanation:

A test is statistically significant at 5% level of significance.

Alternative hypothesis is true (the null hypothesis is rejected).

when p-value < alpha, if p-value < 0.05, we can say p-value < 0.1

"The null hypothesis will also be rejected at 10% level of significance."

Therefore, answer is option c.
