Scenario 2. A researcher is interested in studying whether a new app can help improve the social skills of children with ADHD. She randomly assigns her participants to use the new app for 6 weeks, to attend a face-to-face 6 week social skills group program, or to not receive any treatment (the control group), and compares their social skills. What is the most appropriate test statistic to use to test the hypothesis in scenario 2? A) Correlation Coefficient B) One sample Z-Test C) One-way ANOVA D) Regression Analysis E) Independent samples t-Test F) P-test G) Z-score H) Dependent samples t-Test What is the null hypothesis for scenario 2? A) H0: Mapp= µcontrol B) HO: µ1(app) ≠ µ2(social skills group) ≠ µ3(control) C) HO: µ1(app) = µ2(social skills group) =µ3(control) D) H0: rxy = 0 E) H0: µapp≥ µcontrol F) H0: µ8app ≤ µcontrol G) HO: µposttestA = µpretestB H) H0: µapp= µsocial skills group What is the alternative hypothesis for scenario 2?
