On a recent survey, a business asked respondents the likelihood they would recommend the business to a friend (1 = not at all likely; 10 = very likely). They want to see if there are differences in the likelihood to recommend by education level (High School, Some College, and College Graduate). Therefore, they run a One-Way ANOVA. Use the results below to answer the 3 questions that follow.

What is the test statistic andp-value associated with a test to see if there are any differences among the three group means?

Test statistic = 116.042;p-value = .000

Test statistic = 15.825;p-value = .000

Test statistic = 2;p-value = .000

Test statistic = 3.332;p-value = .038

Which post-hoc test should be used, and how did you arrive at that conclusion?
