Critical Value Chi Square Distribution Table. For upper tail one sided tests the test statistic is compared with a value from the table of upper tail critical values. Since our test statistic is greater than our critical value we reject the null hypothesis.
This means we have sufficient evidence to say the true distribution of customers who come in to this shop on weekends is not equal to 30 on friday 50 on saturday and 20 on sunday. Because of the lack of symmetry of the chi square distribution separate tables are provided for the upper and lower tails of the distribution. 995 99 975 95 9 1 05 025 01 1 0 00 0 00 0 00 0 00 0 02 2 71 3 84 5 02 6 63 2 0 01 0 02 0 05 0 10 0 21 4 61 5 99 7 38 9 21.
Because of the lack of symmetry of the chi square distribution separate tables are provided for the upper and lower tails of the distribution.
0 05 on the left is 0 95 on the right. The areas given across the top are the areas to the right of the critical value. Chi square distribution table d f. For upper tail one sided tests the test statistic is compared with a value from the table of upper tail critical values.
