Question 10 3 pts To test the hypothesis that an intervention involving self-facilitated interprofessional group meetings would result in improvement in wellbeing and satisfaction in the workplace, 60 healthcare workers were interviewed to determine their feelings of satisfaction and wellbeing at work. The healthcare workers were then randomly assigned to two groups. The control group met weekly without any specific guidelines for the discussion content and the treatment group met weekly with a one-page discussion guide addressing themes relevant to challenges in the workplace. After 3 months, researchers re-interviewed subjects and recorded whether each subject felt "more satisfied", "the same" or "less satisfied" at work. The results are shown in the table below.

Which of the following would be an appropriate alternative hypothesis in this study for a chi- square test for homogeneity of satisfaction across treatments? 0 Ha: There is no difference in the distribution of satisfaction across the two treatments 0 Ha: There is no association between satisfaction and treatment 0 Ha: There is a difference in the distribution of satisfaction across the two treatments 0 H3: The proportion of satised workers is the same for both groups. Question 12 3 pts Severe childhood adversity accounts for a large portion of psychiatric illness, and an increased risk for major depressive disorder (M DD). In an observational study, a simple random sample of 160 adults from the Northeast was categorized by whether they currently have or have had MDD, have not been diagnosed with MDD but have been diagnosed with depression at least once, or have no instances of MDD or other types of depression. Each participant was also categorized by whether or not they experienced severe childhood adversity. The data is shown in the table below: Severe Childhood No Severe Childhood Adversity Adversity \" Depression No MDD but Depression . . 27 12 Diagn05|s Researchers are investigating whether the study provides convincing statistical evidence that there is an association between severe childhood adversity and depression.

Product advertisers studied the effects on how popular licensed cartoon characters appearing on food packaging affect young children's taste and snack preferences. Ninety 4- to 6-year-old children were randomly assigned to taste a pair of identical foods either low nutrient (graham crackers) or high nutrient (carrots) presented in packages with or without a popular cartoon character. Children tasted both food items in each pair and indicated whether the 2 foods tasted the same or one tasted better. The results are shown in the table below.
