9. Suppose a researcher used a sample of 200 participants to determine if there is a significant preference between 4 flavors of yogurt. Each individual tastes all 4 flavors and then selects his/her favorite. If the data are evaluated with a one-way Chi-square test using the .05 level of significance, how large does the calculated value need to be
