Another way to think about it is if you know four of these data points and you know the totals, then you could figure out the other five data points. And so now we are ready to calculate a p-value. And you could do that using a calculator and you could do that using a chi-squared table. But let's say we did it using a calculator. And we get a p-value of 0.018. And just to remind ourselves what this is, this is the probability of getting a chi-squared statistic at least this large or larger. And so next, we do what we always do with hypothesis testing.
