You compare Emotional intelligence scores of a sample of boys (age 15) and another sample of young men (age 20). You design a longitudinal study to test your hypothesis that EQ will increase with age from adolescence to early adulthood. Use the proper t-test to see whether emotional intelligence is significantly higher in the older group. Your critical value is 0.05.

What is the independent and dependent variable? What is the null and alternate hypothesis? What would be the correct t-test to use to test this data?
