WebSo, the z score here, z score here is a positive 2.5. If he was below the mean, it would be a negative. So now, we can look at a z table to figure out what proportion is less than 2.5 standard deviations above the mean. So, that'll give us that orange and then we'll subtract that from one. So, let's get our z table. So, here we go. WebNote that z-scores also allow us to compare values of different normal random variables.
