Scenario 1: A local high school wants to see how their AP psychology exam scores compare to the AP psychology exam scores for the whole country. Q1) what is the most appropriate test statistic to use to test the hypothesis in scenario one? A) one way ANOVA B) one sample z-test C) independent samples t-test D) dependent samples t test E) correlation coefficient F) regression G) Z-score Q2) what is the null hypothesis for scenario one? A) H0: X (population) >or = u(Greek mu) (sample) B) H0: m1 (sample) < or = m2 (population) C) H0: X1 (sample) = X2 (population) = X3 (control) D) r > 0 E) H0: X (sample) = u(Greek mu) (population) F) H0: X (sample) > u(Greek mu) (population) Q3) what is the alternative hypothesis for scenario one? A) H1: X not equal to u(Greek mu) B) H1: X1 not equal to X2 not equal to X3 C) H1: m1 < m2 D) r not equal to 0 Scenario 2: A researcher is interested in examining how a new exercise program aimed at body positivity can influence teenagers self-esteem. She randomly assigns teenagers to either engage in the new exercise program for eight weeks (the experimental group) or to a control group that does not do the program and then compares your self-esteem. Q4) what is the most appropriate test statistic to use to test the hypothesis in scenario two? A) Structural equation models B) Z score C) Dependent samples t-test D) one-way ANOVA E) Z test F) independent samples t-test G) Factor analysis H) correlation coefficient Q5) what is the null hypothesis for scenario 2? A) H0: self-esteem in the experimental group = self-esteem in a control group B) H0: Rxy = 0 C) H0: Self-esteem and experimental group is not equal to self-esteem and the control group D) H0: self-esteem in experimental group < self-esteem in the control group E) H0: Self-esteem an experimental group > self-esteem in the control group F) H0: u1(Greek mu) (Group that does the new program close) = u2(Greek mu) (control group 1) = u3(Greek mu) (control group 2) Q6) what is the alternative hypothesis for scenario 2? A) H1: Self-esteem the experimental group < self-esteem in the control group B) Self-esteem an experimental group > self-esteem in the control group C) u1(Greek mu) (Group that does the new program close) not equal u2(Greek mu) (control group 1) not equal u3(Greek mu) (control group 2) D) H1: RXY = 0 E) Self-esteem the experimental group = self-esteem in the control group F) Self-esteem the experimental group not equal self-esteem in the control group Q7) what is the independent variable for scenario 2? A) The participants B) there is no independent variable for this type of analysis C) self-esteem D) The body positive exercise program E) The researchers Q8) what is the dependent variable for scenario 2? A) there is no dependent variable for this type of analysis B) The body positive exercise program C) The researchers D) The participants E) Self-esteem
