So whenever we're answering these types of questions, the first thing that we need to do is to define our hypothesis.
00:06
In this case, we are saying the mean cells levels are identical.
00:12
They are identical for the three box colors.
00:16
So what this means is the alternative is going to be saying these are different.
00:21
So now that we have defined our null and its alternative, what we then need to do is to look at a test statistic.
00:31
And for that test stick, what we need to do is to look for its corresponding critical value.
00:37
And the difference between those two parameters is what is then going to help us determine if we should accept this initial assumption.
00:45
Now based on the information that we have been given, we can use a kai squared as our test statistic.
00:52
That is, we can use a kai square distribution.
00:56
So based on the information that we have been given, this, for example, for example, look at the degrees of freedom that we are dealing with...
