Hello All,
I have a practical problem that I would appreciate your advice on.
The weights of individual livestock at age X are normally distributed with mean A and standard deviation of B.
Similarly livestock at age X+1, X+2 etc etc also follow a normal distribution with their own mean and Standard deviation.
Normally only one age band is processed at a time. However, if more than 1 age band were to be processed, what would the mean weight and standard deviation of the mixed animals be.? Is it as simple as taking an average of the means and summing the variances?
Many Thanks for any help you can offer.
