Sorry, I was having difficulty with the equation editor on here. I've attached my problem as a picture file. I need to show that the two equations are equal, and I'm not sure where to begin. Thanks!

Assuming that is the conjugate of the complex number , that statement is false. . Note that and

@Plato - x-bar is not a conjugate @CaptainBlack - In your process, what happens to the x double bar? How does that get factored out?

x-bar is the mean. I was under the assumption that x double bar is the average of the means. I'm not aware that x double bar can be transformed back to regular x bar. Am I missing something?

Am I missing something? x double bar as you call it is the mean of the mean, but the mean is just a number, its mean is itself. To see this just look at your definition of a mean. CB
