Math Statistics Compute the p-value for a Chi-Squared Goodness of Fit Test with a sample size of 600, 7 categories and a test statistic of 10.7777. Round to the fourth. Compute the p-value for a Chi-Squared Goodness of Fit Test with a sample size of 600, 7 categories and a test statistic of 10.7777. Round to the fourth.
WebThe degrees of freedom is calculated as df = k-1, where k is the number of categories. In this case, k = 4, so df = 3. Using alpha = 0.05, the critical value of chi-square with 3 degrees of freedom is 7.815. e. Since the calculated X^2 statistic (4.09) is less than the critical value of chi-square (7.815), we fail to reject the null hypothesis. WebThus, the critical value of chi-square for p=0.05 with 2 d.f. is 5.991. Earlier, remember, we considered a value of 4.901. Notice ... the chi-square goodness-of-fit test works pretty well. The test statistic usually referred to as "chi-square" (unfortunately, in my opinion) is calculated by comparing observed results to expected results. ...
