Hi, I'ld like to know if anyone knows how to find the 'z' score inrelation to a percentage degree of confidence. The question is: Determine the z score that would give a result with a degree of confidence of 95%.(adsbygoogle = window.adsbygoogle || []).push({});

I know that it is, 1.9600. However, I would like to know how to figure this out mathematically.

Thanks,

Sirsh.
