Joint CI
Posted:
Sep 25, 2013 6:13 AM


I have two sets of normally distributed real numbers randomly drawn from two populations with the same mean, but with different variance.
I need to calculate the overall mean of the two sets (both have the same mean) and the confidence interval for that mean.
I know how to calculate the CI for the mean of each set, but how to calculate the CI for the overall mean?
Thank you Cristiano
