All right, so in this problem, it looks like we were wanting to run a hypothesis test.
00:04
I'm going to use technology in order to do it just to make the computations easier for us.
00:08
Now, we are dealing with a mean.
00:12
It looks like we are dealing with a mean.
00:14
And so since we're dealing with a mean with more 30 people in the sample, we'll go to stat.
00:22
We're going to talk about z stats.
00:24
If you don't have access to stat crunch, you can use a similar program.
00:27
You just google something similar as z stat calculator.
00:31
And then we have the summary here.
00:35
Now, our sample mean that we're told, okay, the average was 2260.
00:41
So we're going to put our average here is 2260...
