8. A special education researcher implemented an applied behavior analysis plan for n = 6 students in order to reduce distractive and disruptive behaviors in the classroom. In order to evaluate the effectiveness of positive reinforcement, distracting behaviors were recorded for one week; these measurements served as phase 1. At the end of the intervention phase (end of week 2) disruptive behaviors were recorded. Using a one-tailed test, with a .05 level of signicance, determine whether the intervention decreased disruptive behaviors in the classroom. \"-- -mn nun \" "n a.
