You had your sampling distribution of the sample mean. We know what the mean of that was, it's 1.2 seconds, same as the population mean. We were able to estimate its standard deviation using our sample standard deviation, and that was reasonable because it has a sample size of greater than 30, so we can still deal with a normal distribution for the sampling distribution. 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.
