All right, here we have that the random variable z falls a normal distribution.
00:05
That's what we say with a capital m with a standard deviation of 0 and 1, which it says that the mu here is equal to 0.
00:16
The sigma is equal to 1, right, which says that it's right in the middle.
00:20
Our mean is right in the middle.
00:22
And each of our standard deviations is just 1.
00:24
All right, so the way that we find this in a, using a calculator, we can use a calculator or a table.
00:32
The table is kind of the old school way of doing it, and it's kind of confusing, but you can use your calculator.
00:37
If you find, if you hit the second and then the stat button, right, right, if you hit that, then you'll find in the drop down menu the function called inverse norm, right? and then all you need to do is make sure that these parameters are set up, that your mu is equal to zero, that your sigma is set up to one...
