We believe there will be significant differences between age groups and the importance of ethnic food choices available. Using the One-Way ANOVA results, answer the following questions: a) (3 points) Test for overall differences between age groups. Report the conclusion in a succinct sentence or two, including the value of your test statistic and the p-value. b) (2 points) Report whether the group sizes among the each age group are about the same. Also report if variances are equal. Given this, what post-hoc test should you run? c) (2 points) Run a post-hoc analysis using the post-hoc test from part (b). Report which age groups are significantly different from each other along with the mean difference for each significant difference.
