Courtney and Lexi wondered if the distribution of color was the same for name-brand gummy bears (Haribo Gold) and store- brand gummy bears (Great Value). To investigate, they randomly selected 6 bags of each type and counted the number of gummy bears of each color. The data are presented in the table. Courtney and Lexi use a chi-square test for homogeneity to assess differences between the gummy bear brands. Do these data provide convincing evidence that the distributions of color differ for name-brand gummy bears and store-brand gummy bears at the a = 0.05 level? Survey Type Which of the following is false? Name Store Total Red 137 212 349 O Because the P-value of 0.7698 > a = 0.05, we fail Green 53 104 157 to reject Ho.
