In this analysis, assume all assumptions have boon met and at = 9.115. Task 4 ANOVA {Thinking About the Research Question} Answer these questions succinctly {use the following numbering in your submission; you must not re-wnte the question]: 1. What is the independent vaJiable {IV}? What type of variable {quantitative or qualitative) is the IV? If it is qualitative. state the number of levels {categories} in the variable, according to your analysis. 2. What is the dependent variable {DY}? 1'i'ufbat type of variable {quantitative or qualitative} is the DIV? If it is qualitative, state the number of levels {categories} in the variable, according to your analysis. 3. Briey explain {in 1-4 sentences] why an ANDVA is the most appropriate analysis for this research question. 4. What is the null hypothesis for this research question? What is the alternate hypothesis? Write these in words only {statistical notation not necessary}
