And so if we just scan this, we're looking for 95%. We have 0.9495, we have 0.9505. So I'll go with this, just to make sure we're a little bit closer. So this z value, and the z value here is 1.6, and the next digit is 5. 1.65. So this critical z value is equal to 1.65. So the probability of getting a z value less than 1.65, or even in a completely normalized normal distribution, the probability of getting a value less than 1.65, or in any normal distribution, the probability of being less than 1.65 standard deviations away from the mean is going to be 95%.
