In a hypothetical research study, the grade point averages of two groups of n = 10 high school students were compared. The first sample (n_{2} = 10) had been exposed to little screen time during the first five years of their lives and the second sample (n_{2} = 10) had been exposed to more than three hours of screen time per day during the first five years of their lives. What is the degrees of freedom for this independent samples t-test?
