So I'll make the null hypothesis that the owner's distribution, so that's this thing right here, is correct. And then the alternative hypothesis is going to be that it is not correct, that it is not a correct distribution, that I should not feel reasonably okay relying on this. It's not correct. I should reject the owner's distribution. And I want to do this with a significance level of 5%. Or another way of thinking about it, I'm going to calculate a statistic based on this data right here. And it's going to be a chi-square statistic, or another way to view it is that that statistic that I'm going to calculate has approximately a chi-square distribution.
