So the standard deviation of our sampling distribution is going to be, and we'll put a little hat over it to show that we approximated the population standard deviation with the sample standard deviation. So it is going to be equal to 0.5 divided by 10, so 0.05. And so what is the probability of getting 1.05 seconds? Or another way to think about it is, how many standard deviations away from this mean is 1.05 seconds? And what is the probability of getting a result at least that many standard deviations away from the mean? So let's figure out how many standard deviations away from the mean that is. And essentially, we're just figuring out a z-score for this result right over there.
