... This test statistic can be compared to the chi-square value from the table with 10-1 = 9 degrees of freedom and a one-tail area of 0.05. That value is 16.9190. Since 2 135.49 16.9190 , the null hypothesis is rejected. This means that the variation standard is being exceeded based on these data ...
