We want to find the expected cell count for a particular cell on this graph.
00:05
So when we say expected cell count, expected means we are saying that there is no link between education level and belief in the theory of evolution.
00:19
So no link.
00:23
So to approach this, you need to find the proportion of a population who believe it, who rather do not believe in evolution.
00:32
So the probability of do not believe, if we just ignore, education level, is 254 out of 1 ,018.
00:45
So that is the proportion of the population in general who do not believe.
00:50
We need to take that and apply it specifically to the college graduates.
00:56
So we're going to look at how many college graduates they are and say, okay, let's expect that this proportion won't believe.
01:03
And we'll see what we get.
01:06
So there are 228 college graduates.
01:11
We expect a proportion of 254 over 1 ,018, to not believe...
