Sketch the standard Normal curve for the test statistic and

Sketch the standard Normal curve for the test statistic and mark off areas under the curve to show why a value of that is significant at the 1% level in a one-sided test is always significant at the 5% level. If is significant at the 5% level, what can you say about its significance at the 1% level? A. A test that is significant at the 5% level coincides with test that is significant at the 1% level. B. A test that is significant at the 5% level is not necessarily significant at the 1% level. C. A test that is significant at the 5% level is always significant at the 1% level. D. It is impossible to say anything about it.
