Dr. Caldwell was also interested in learning whether the anxiety of child victims is related to whether they testify in court. She conducted another research study in which she compared the anxiety levels of 10 children who testified to the anxiety levels of 10 children who did NOT testify. She measured the children’s anxiety using the same test described earlier - the Beck Anxiety Inventory for Children (BAI-C). The scores of the 20 children are as follows: Testified​​Did NOT Testify​55​54​57​62​50​72​62​69​66​73​48​58​71​75​60​63​70​70​52​66 11. Conduct an independent measures t-test to determine whether Dr. Caldwell can conclude that there is a significant difference between child victims who testify and those who don’t with respect to anxiety. Show all 4 steps of hypothesis testing, and calculate a measure of effect size. Use a 2-tailed test with α = .05 Step 1: Step 2: Step 3: show calculations and values for: M and SS for each group, the pooled variance, the standard error of the mean difference, and the t. Step 4: Calculate a measure of effect size: Write results in APA format.
