Extracted text: 109. Suppose a study was done to replicate the results of the 2003 study by Wansink et al. in Physiology A Behavior, Participants were asked to rate different food items as "comfort foods" on a scale of 1= strongly disagree to 5 = strongly agree. Results are displayed below for participants' ratings of "Vegetables, Casseroles, Sides" as comfort food. Is there evidence that at least one age group has a different average rating for "Vegetables, Casseroles, Sides" as comfort food? %3D Subject 18-34 35-54 55+ 3 1 3 3 3 3 3. 3 3. 4 4 3 3 2 3 6 3 4 7. 3 3 3. 8 3 9 3 3 10 3 3 ch (a) State the hypotheses for the test. h o d UE) ds (b) Use the calculator to find the test statistic and p-value of the test.
