Question

Respond to the following questions using this partially completed one-way ANOVA table: Based on the analysis of variance F-test,what conclusion should be reached regarding the null hypothesis? Test using a significance level of 0.01. A)Since 7.948 > 2.8778 accept H₀ and conclude that all population means are the same. B)Since 14.667 > 2.8778 accept H₀ and conclude that all population means are the same. C)Since 7.948 > 2.8778 reject H₀ and conclude that at least two populations means are different. D)Since 14.667 > 2.8778 reject H₀ and conclude that at least two populations means are different.

Quizplus · Accepted Answer

The F-test value of 14.667 is greater than the critical value of 2.8778 at a significance level of 0.01. Therefore, we reject the null hypothesis (H₀) and conclude that at least two population means are different.
