And using that, we saw that the result, the sample mean that we got, the 1.05 seconds, is three standard deviations below the mean. So if we look at it, let me just redraw it with our new hypothesis test. So this is the sampling distribution. It has a mean right over here at 1.2 seconds. And the result we got was three standard deviations below the mean. One, two, three standard deviations below the mean. That was what our 1.05 seconds were.
