So this distance right over here, where this is 94%, this number of standard deviations, that is z star right over here. Now, all we have to really do is look it up on a z table, but even there we have to be careful. And you should always be careful which type of z table you're using, or if you're using a calculator function, what your calculator function does. Because a lot of z tables will actually do something like this. For a given z, they'll say, what is the total area going all the way from negative infinity up to including z standard deviations above the mean? So when you look up a lot of z tables, they will give you this area. So one way to think about this, we wanna find the critical value, we wanna find the z that leaves not 6% unshaded in, but leaves 3% unshaded in.
