A random sample of 40 children In 5th grade is selected from a local ele- mentary school and randomly assigned to one of two groups: Group A (intervention group) and Group B (comparison group). Both Group A and Group B were assessed before the intervention on the Strengths and Difficulties Questionnaire (SDQ) and there were no real differences be- tween the group means and standard deviations. Then, for 12 weeks, Group A participated in a mindfulness intervention and at the end of the 12 weeks both groups repeated the SDQ. The expectation was that SDQ scores for Group A would decrease as a result of the intervention. The post-intervention data for both groups was analyzed and the follow- ing finding reported: t= -0.693 Respond to questions 6 - 11 to demonstrate your understanding of Bayesian Hypothesis Testing. 6.
