This is what the distribution of our random variable z is going to look like. I'll do it in the z's color so that it's clear. And so you can see two things. One, the mean for sure shifted. The mean here for sure got pushed out. It definitely got scaled up. But also, we see that the standard deviations got scaled, that the standard deviation right over here of z, that this has been scaled, it actually turns out that it's been scaled by a factor of k. So this is going to be equal to k times the standard deviation of our random variable x.
