The test statistic for any test is always greater … WebStep 4. Since the CEE factor has two levels and the GPA factor has three, I = 2 and J = 3. Thus the test statistic follows the chi-square distribution with df = (2 − 1) × (3 − 1) = 2 degrees of freedom. Since the test is right-tailed, the critical value is χ2 0.01.

In what interval range does the P value fall, if a chi-square test of experimental data produces a chi-squarevalue of 7.83 with 4 degrees of freedom?b. Is the result sufficient to reject the chance hypothesis?PLEASE EXPLAIN. WebThe following is the chi-square distribution with 4 df. In the first plot, we see that when the χ^2 value = 9.49, the area to the right or the p-value = 0.05. In our contingency table, the χ^2 value = 20.48 (plotted as a vertical line in the second plot), so the p-value is very much smaller than 0.05. billy pull on
