Homework Help: Question about hypothesis testing

  1. Apr 5, 2005 #1
    i'm getting my concepts very confused now...

    so the formula for the normal distri is (y - u)/(sigma)/((sqroot(n)).

    so if I want to test y, I set that formula = to alpha(where alpha is the confidence level).

    that is if it is one sided. if it is 2 sided, do I still set it to alpha, or alpha/2?

    i'm pretty sure if it's 2 sided then you set it to [tex]\frac{\alpha}{2}[/tex]
