how to check significance testing?

hi, I am new to MATTLAB. I have made this program function [out] = significance(z,t); if t <= z < 2*t; out = 1 else if Z < t out = 0 else if z >= 2*t out='null' end end end BUT when z >= 2*t out=1 is displayed instead of out='null'. can anyone help me so that I can get out='null' when z >= 2*t.

That's because your conditions are wrong. If z>=2*t, then that means you have already satisfied the condition t<=z. And so you always will get out = 1
