We can say that the mean of our random variable y is equal to the mean of x, the mean of x of our random variable x plus k, plus k. You see that right over here. But has the standard deviation changed? Well, remember, standard deviation is a way of measuring typical spread from the mean, and that won't change. So for our random variable x, this length right over here is one standard deviation. Well, that's also going to be the same as one standard deviation here. This is one standard deviation here. This is going to be the same as our standard deviation for our random variable y.
