What is the basis for your choice? 4.2 What test assumptions and restrictions are needed for the method you selected? 4.3 Use proper hypothesis testing method to analysis data and provide results and conclusion Alpha level = 0.05. Your results should include Hypothesis test scores, results, corresponding conclusions, and effect size
