Hey guys hope you all doing very well. Im currently revising the cent. Lim. Theo. And i have this equation
Z=[ x-u] / [ sigma/ sqrt n]
x : sample mean
u: population mean
Sigma: population std dev
N : nbr of samples
i want to know if the denominator is the std dev of the sample or if not what is it ?
Thank you alot
