WebAnd we got a chi-squared value. Our chi-squared statistic was six. So this right over here tells us the probability of getting a 6.25 or greater for our chi-squared value is 10%. If we go back to this chart, we just learned that this probability from 6.25 and up, when we have three degrees of freedom, that this right over here is 10%.
