A dietician wants to see if there is any difference in the effectiveness of three diets. Eighteen people, comprising a sample, were randomly assigned to the three diets. Below you are given the total amount of weight lost in a month by each person. Diet ADiet BDiet C141225181032202218121214201617181214 What would you advise the dietician about the effectiveness of the three diets?

A researcher is studying the effects of three different diets on weight loss. She randomly assigns participants to one of the three diet plans and records their weight loss after 4 weeks. Which of the following is the primary reason for using ANOVA in this scenario? A.A) To determine the average weight loss for each diet.B. B) To compare the effects of the three diets to see if there is a significant difference in weight loss among them.C.C) To determine which diet has the largest standard deviation in weight loss.D. D) To compare the difference in weight loss between each pair of diets.

In which one of the following situations would it be most appropriate to use an ANOVA to analyze the data? In order to determine the effectiveness of different diet plans, 90 people are randomly assigned to one of three groups: (1) low calorie diet, (2) low-fat diet, or (3) low-carb diet. At the end of 60 days, the number of pounds lost was recorded for each of the participants. A researcher is interested in determining the most effective format for advertising. He randomly assigns 60 people to one of three groups: (1) television commercial, (2) radio commercial, or (3) magazine advertisement. Group members review the commercial and then report whether or not they would buy the product.

You obtained a significant test statistic when comparing three treatments in ANOVA. What is the conclusion?
