Refer to Table VI in Appendix A. Because of space restrictions, the numbers of degrees of freedom are not consecutive. For instance, the degrees of freedom for the numerator skips from 24 to 30. If you had only Table VI and you needed to find F0.05 for df = (25, 20), how would you do it?
Answer to relevant QuestionsState the four assumptions required for one-way ANOVA. How crucial are these assumptions? Discuss two methods for checking the assumptions of normal populations and equal standard deviations for a one-way ANOVA. Show that, for two populations, MSE = s2p, where s2p is the pooled variance defined in Section 10.2 on page 397. Conclude that √ MSE is the pooled sample standard deviation, sp. Suppose that x is a normally distributed ...a. Compute SST, SSTR, and SSE by using the computing formulas given in Formula 13.1 b. Compare your results in part (a) for SSTR and SSE with those in Exercises 13.24–13.29, where you employed the defining formulas. c. ...In Section 13.2, we considered two hypothetical examples to explain the logic behind one-way ANOVA. Now, you are to further examine those examples. a. Refer to Table 13.1 on page 528. Perform a one-way ANOVA on the data and ...
