Please specify the sample size.

if the sample size is large the test statistics is

Z=(X(bar) – Mu)/ (sigma/Sqrt(n))

if the sample size is small the test statistics is

t=(X(bar) – Mu)/ (s/Sqrt(n)) where s= (n1(s1*s1)+n2(s2*s2))/(n1 + n2 -2)

Dear all Statistician,

Suppose I have a series of observations like x1, x2,................, xn. Now I want to test the following hypothsis:

H0: x[i] comes from N(mu1, sigma1)

H1: x[i] comes from N(mu2, sigma2)

Can anyone tell me that how can I test that, what will be test statistic, what will be it's distribution undel null etc?

your help will be highly appreciated.

Thanks ans regards;

stat
