How do you find Z(alpha/2 ) for a 94% confidence interval? I know how to find normal c.i's such as 90% 95% 99%...

i know alpha/2 = 0.03. And the answer is 1.88. But I don't know how you're supposed to find it.

I have the critical values of t table and normal curve table ( Z).

edit: nvm figured it out
