Say you have a confidence interval of 99% confidence, and the range is (-12, 1.4). If you have a number that lies outside of that range (let's say 1.9), then you can reject [itex]H_0[/itex] (and accept [itex]H_a[/itex]) at [itex]\alpha = .01[/itex]. If the number does lie inside that range (let's say -3), then you accept [itex]H_0[/itex] (and reject [itex]H_a[/itex]).

a confidence level always has a significance level associated with it, so no.

Confidence level = 1 - significance level
