\fWhat is the test statistic and does the experiment conclude that there is a difference in mean weight loss among the three diets at the 0.05 level of significance? 13.47 and no there is not a difference in diet. O 2.25 and no there is no difference in diet 2.25 and yes there is a difference in diet O 13.47 and yes there is a difference in diet.The following case applies to questions 1-3: Clients can choose between three diets at a weight-loss treatment center. An experiment was performed to determine if there is a difference between the diets. Fifteen patients were randomly selected and divided evenly into three groups of five for each diet.

All of the diet variances are equal. O At least one of the diet means is not equal. None of the diet variances are equal. O All of the diet means are equal. O None of the diet means are equal
