Critical Value Chi Square Distribution Chart. For a two tailed case the critical values correspond to two points on the left and right tailes of the distribution with the property that the sum of the area under the curve for the left tail from the left critical point.

Since our test statistic is smaller than our critical value we fail to reject the null hypothesis.

If the chi square statistic that we calculate from our data is greater than or equal to19 675 then we reject the null hypothesis at 5 significance. Since our test statistic is smaller than our critical value we fail to reject the null hypothesis.
