Now Dr. Smith was interested in the effects of testifying in court on child victims of abuse. She conducted a research study in which she compared the anxiety levels of children who testified to the anxiety levels of children who didn't testify. Once again, she measured the children's anxiety using the Beck Anxiety Inventory for Children (BAI-C). The results are as follows:

a. Conduct an independent measures t-test to determine whether Dr. Smith 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 (using = .05), clearly labeled, and remember to calculate a measure if effect size if it's appropriate to do so. Show all the steps.
