I run an algorithm that outputs a normally distributed random number with unknown mean and variance. I need to know the mean of those numbers.
To do that, i repeatedly run that algorithm to obtain many numbers, then I calculate the mean and the confidence interval for the mean.
Over the last years, I ran 8 of those simulations with different parameters (the population mean doesn't change).
For each simulation I have: the number of the random numbers, their mean and the confidence interval for the mean.
Since I need only a single value for m, I calculated the weighted mean that minimizes the variance of the 8 means.
Is there any way to calculate the confidence interval for the weighted mean?
Thank you
