Or that the mean with the drug is less than 1.2 seconds. Now if you do a one-tailed test like this, what we're thinking about is, what we want to look at is, we have our sampling distribution. Actually I can just use the drawing that I had up here. 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.
