So our alpha is 10%. So what we're going to do is figure out what is our critical chi-square statistic that gives us an alpha of 10%. If this is more extreme than that, if the probability of getting this is even less than that critical statistic, it will be less than 10% and we'll reject the null hypothesis. If it's not more extreme, then we won't reject the null hypothesis. So what we need to do is to figure out with a chi-square distribution and 2 degrees of freedom, what is our critical chi-square statistic? So let's just go back. So we have 2 degrees of freedom here and we care about a significance level of 10%.
