16. The following data were obtained from an independent-measures research study comparing three treatment conditions. Use an ANOVA with ? = .05 to determine whether there are any significant mean differences among the treatments. Treatment I II III 5 2 7 1 6 3 2 2 2 3 3 4 0 5 5 1 3 2 2 0 4 2 3 5 17.

For Exercises 9 through $13,$ do a complete one-way ANOVA. If the null hypothesis is rejected, use either the Scheffé or Tukey test to see if there is a significant difference in the pairs of means. Assume all assumptions are met. Emergency Room Visits Fractures accounted for $2.4 \%$ of all U.S. emergency room visits for a total of $389,000$ visits for a recent year. A random sample of weekly ER visits is recorded for three hospitals in a large metropolitan area during the summer months. At $\alpha=0.05,$ is there sufficient evidence to conclude a difference in means? (TABLE NOT COPY)
Analysis of Variance
The Scheffe Test and the Tukey Test
The following data were collected from a repeated-measures study. Perform an ANOVA. Use a .05 alpha level. (10 POINTS) Treatment A B _____________ G = 36 2 6 2 6 ?X2 = 192 4 4 4 8 ______________ T = 12 T = 24 SS = 4 SS = 8 1) State the null hypothesis. 2) Calculate necessary statistics (USE AN ANOVA even though K=2, and ??= .05). 3) Make a decision about your null hypothesis and explain what that decision means. 4) Make a conclusion about your IV and DV that includes an APA format summary of your statistical analysis.

For Exercises 9 through $13,$ do a complete one-way ANOVA. If the null hypothesis is rejected, use either the Scheffé or Tukey test to see if there is a significant difference in the pairs of means. Assume all assumptions are met. Per-Pupil Expenditures The expenditures (in dollars) per pupil for states in three sections of the country are listed. Using $\alpha=0.05,$ can you conclude that there is a difference in means? (TABLE NOT COPY)
