Homework Statement
I'm trying to formulate a formula based on an experiment I did.
Homework Equations
The Attempt at a Solution
where
x_1 = mean (one of 5 mean values)
x_i = value of variables (there are 4 of them added together)
n = number of variables
My problem is, for the left hand side of the formula, I want to show that there are 5 means, so x_1 to x_5 = the right hand side as shown
I'm not sure how to show this mathematically.
Wonder if anyone might be able to help.
Thanks.
