New research suggests that watching television, especially medical shows such as Grey's Anatomy and House can result in more concern about personal health (Ye, 2010). Surveys administered to college students measure television viewing habits and health concerns such as fear of developing the diseases and disorders seen on television. For the following data, students are classified into three categories based on their television viewing patterns and health concerns are measured on a 10-point scale with 0 indicating "none."

a. Use an ANOVA with α = .05 to determine whether there are significant mean differences among the three groups.
b. Compute η2 to measure the size of the effect.
c. Use Tukey's HSD test with α = .05 to determine which groups are significantly different.
