So on this problem, we're doing with the normal distribution.
00:04
I don't know if you're using technology or not to do it.
00:06
I will use technology here.
00:07
It just makes the calculations much easier.
00:10
In order to do this, we're going to go to a normal calculator.
00:13
I use what's called stat crunch.
00:14
You don't have to use stat crunch.
00:16
If you just google normal calculator, it should give you something that works just exactly like this does here.
00:22
Now, we're told we have a mean of 10 and a standard deviation of 4.
00:25
And so let's put it in our mean of 10 and our standard deviation of 4.
00:33
Now, part a, we want to find the probability of measurement exceeds 13.
00:38
For it to exceed 13, we want to be greater than 13.
00:44
I'm going to compute that gives us our 0 .2266 down here.
00:49
So that would be the probability that exceeds 13...
