WebBecause i was curious, i wanted to know the average monthly mean power, and its standard deviation. Through induction, we need 12 normal distributions which: sum to a mean of 10,358; sum to a variance of 647,564; That would be 12 average monthly distributions of: mean of ; variance of ; standard deviation of sqrt(53963.6) = 232.3 WebThis means that the sum of two independent normally distributed random variables is normal, with its mean being the sum of the two means, and its variance being the sum of the two variances (i.e., the square of the standard deviation is the sum of the squares of the standard deviations).
