Question:
For Exercises 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.
Fractures accounted for 2.7% of all U.S. emergency room visits for a total of 454,000 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 α = 0.05, is there sufficient evidence to conclude a difference in means?
