So I could just write it, I'm just writing it all the different ways that you might see it, because sometimes the notation is the most confusing part in statistics. And so this is going to be the square root of what? Well, the variance of a binomial variable is going to be equal to the number of trials, times the probability of success in each trial, times one minus the probability of success in each trial. And so in this context, this is going to be equal to, you're gonna have the 500, 500, times 0.02, 0.02, times one minus 0.02 is.98. So times 0.98, and all of this is under the radical sign. I didn't make that radical sign long enough. And so what is this going to be?
