You are interested in studying whether mentoring for at-risk youths improves their outlook for their future. You take a sample of 200 at-risk youth and measure their outlook for the future before the mentoring program begins using 5 questions that have a response set from 1 (bleak) to 5 (bright). You then add their responses together to get a single variable that has a possible range of 1 to 25. You then measure their outlook after they complete the program. What statistic would you calculate to test your hypothesis? Dependent Samples T-Test Chi-Square Correlation Independent Samples T-Test
