So we could say that this is going to be approximately equal to our sample standard deviation divided by the square root of 100, which is going to be equal to our sample standard deviation is 0.5 seconds. And we want to divide that by square root of 100 is 10. So 0.5 divided by 10 is 0.05. 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?
