Data from the sample are provided in the following table: Recovery Technique Traveler Type I [I III 62 84 9? 56 T3 69 I52 60 7? 3. Conduct a one-way ANOVA with Recovery Technique as your treatment effect. Clearly mention your null and altemate hypotheses, calculations, and your conclusion. 4. Conduct a randomized complete block ANOVA with Traveler Type as your blocking effect. Clearly mention your null and alternate hypotheses, calculations, and your conclusion. 5. How do results change from (3) to (4)? Why
