The significance level, α, is demonstrated with the graph below which shows a chi-square distribution with 3 degrees of freedom for a two-sided test at significance level α = 0.05. If the test statistic is greater than the upper-tail critical value or less than the lower-tail critical value, we reject the null hypothesis. Since the critical value for the alpha of .05 (95% confidence) for df=2 is 5.99 and our chi-square statistic value 16.3, is much larger than 5.99, we have sufficient evidence to reject our Null For df > 90, the curve approximates the normal distribution.
