If $_0$ cannot be rejected at the $5$% significant level, is a test at the $1$% is required?
How to explain this question? Any hint?

If it can't be rejected at the 5% but it could be rejected at the 1%, and there is a need to know whether that happens, how are you going to find out otherwise? – Nij May 21 '16 at 10:39
