2. Aly measures students' anxiety for the final exam in Junker's PSYC-211 course before and after the review session the week before Final's week. Anxiety was measured on a scale from 1 to 10 with 10 being extremely anxious. a. What statistical test should Aly use to analyze the results of her study? (1 point) A) Independent-samples t-test B) Dependent-samples t-test C) ANOVA D) Correlation b. Justify your response. (2 points) 3. Lieutenant Morgan notices that during some months, her murder case load in Miami decreases substantially. She hypothesizes that temperature is related to number of murder cases. To better understand this, she notes the mean temperature each month and the number of murder cases on those months. Her results indicate that as temperature increases, the number of cases also increases a. This study's design can be described as (1 point) A) Descriptive B) Correlational C) Quasi-Experimental D) Experimental b. Justify your response. (2 points) Fill in the blanks below. (4 points) 4. A dependent-samples t-test is used when there are (A; 1 point) levels of an independent variable and a (B; 1 point) design. On the other hand, an independent-samples t-test and an ANOVA are used when there is a (C; 1 point) design. For all of these statistical tests, there must be a (D; 1 point) dependent variable.

Amy and Bernadette are developing a new drug to reduce extreme social anxiety to help their friend, Rajesh, speak to women. They test the efficacy of their new drug by randomly assigning 20 men with extreme social anxiety to either take their new drug for five weeks or to take a placebo for five weeks. After five weeks, they ask the men on a scale from 1 to 10 how anxious they feel (with 1 being not at all and 10 being extremely). a. Their study design can be described as A) Descriptive . (1 point) B) Correlational C) Quasi-Experimental D) Experimental b. Justify your response. (2 points) c. What statistical test should Amy and Bernadette use to analyze their results? (1 point) A) Independent-samples t-test B) Dependent-samples t-test C) ANOVA D) Correlation d. Justify your response (2 points) e. Suppose that Amy and Bernadette run the statistical test and find that the people who take the new drug have a mean 4 and the people who take the placebo have a mean of 7. The p value of the test is .002 and the effect size (Cohen's d) is 1.80. Should they tell Rajesh that the drug works and suggest that he take it? Why or why not? *note* be sure to comment on both the p value and the effect size and means (4 points)
