The dataset you will use for this quiz contains data from a sample of approximately 1300 adolescents who had been arrested for a felony-level crime. For this quiz, you will be focusing on the measure of impulse control (Impulse_Control). The scale used to measure impulse control ranges from 1-5, with greater scores corresponding to the adolescent having better impulse control. We are interested in comparing this sample of adolescents' impulse control to the amount of impulse control as measured in the full population of all adolescents in the nation. The mean of impulse control in the national population of adolescents equals 3.82. Conduct a one-sample t-test comparing impulse control for the adolescents in our sample to the impulse control for the national population of adolescents. Report your results below by filling in the correct value for each piece of information that would be required to report your results in the following format: t(_______ ) = ________, p _________

Cohen's D effect size is -.797

he mean level of impulse control for the adolescents in our dataset is M = 3.07
