Question: The first question involves a parent participation study regarding the benefit of a parent attending stress management sessions while a child is receiving speech therapy. The theory is that if parents are more relaxed at home, communication situations will be less stressful for the child and fluency will improve. In this study, parents elected to attend or not attend the stress management sessions. Of 40 school-age children enrolled in therapy, parents of 31 children attended the stress management sessions and parents of 9 children did not. Among the 40 children who entered therapy with significant dysfluency in speech, 31 showed substantial improvement at the end of therapy and 9 demonstrated little or no improvement.

Using the detailed information shown below, determine the relationship between parent participation in stress management and improved fluency among their children following speech therapy. If the relationship is statistically significant, with an alpha of 0.05, conduct the appropriate follow-up test to determine the strength of the relationship.

State the question in the form of a null hypothesis and conduct the requested computations. Provide an interpretation of your results. Show your work.
