There is a marketing researcher who wants to test the effectiveness of a new commercial by giving participants a survey asking their likelihood of buying a certain cleaning product where 1= not at all likely and 5= extremely likely. The participants will be given the questionnaire before and after watching a show that advertised the cleaning product during commercial breaks. We must Test the hypothesis that the commercial produced an effect on these scores using alpha = .05. list conclusions using variable names and calculate Cohen’s d, if applicable. Step 1: Ho: H1: Step 2: Critical region: Step 3:tobt = Step 4:Which one: fail to reject H0/reject H0 Did the commercial have a statistically significant effect? YES/NO What is the research design used? What is the appropriate statistical analysis?
