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 compare your conclusion to that stated in the corresponding “What Does it Mean?” box. Use α = 0.05.
b. Repeat part (a) for the data in Table 13.2 on page 528.
Apply Procedure to perform a one-way ANOVA test by using either the critical-value approach or the P-value approach.
