hey guys, some hopefully easy stat questions if you will(adsbygoogle = window.adsbygoogle || []).push({});

Im wondering about translating one statistical distribution to another, like going from:

Bin(n,p) to N(np,sqrt(npq)) where q=1-p

or that Po(au) is roughly equal to N(xu,sqrt(xu))

Im mostly sitting scratching my head on which method to use on each and every problem Im solving (Im studying for an exam in march). is there any chart or a really good and lightweight summary somewhere that can shed some light on this? like which method to use and how you can and why you need to translate them to another method, like in the examples above

Im also wondering when you need to use a two-sided interval, like youre going from a 95% to 97.5% by using 1-a/2 where a is the level

I could really use some help and would be grateful for any input

thanks

# Statistics, how do you translate Bin(n,p) to say N(,) etc
