And if we want it in terms of standard deviations, we want to divide it by our best estimate of the sampling distributions standard deviation, which is this 0.05. So this is 0.05. And what is this going to be equal to? z, this result right here, 1.05 seconds. 1.2 minus 1.05 is 0.15. So this is 0.15 in the numerator divided by 0.05 in the denominator. And so this is going to be 3.
