This part focuses on two tables:
Table 1 examines whether different demographics are independent or dependent of parenting status (grandparent vs. parent). The characteristics are gender, age, education level, income category, MSA code, number of children, gender of child, age of child, child’s history of asthma, child received flu shot.
Table 2 examines whether health factors of the caregiver are related to parenting status (grandparent or parent). The indicators are the presence of arthritis, COPD, diabetes, asthma, cancer, heart attack, stroke, angina, and kidney disease, as well as self-rated health status, number of days per month physical health is not good, limitation in activity in the past month, number of days mental health was not good during the past month, presence of depressive disorder, physical exercise in last month, BMI category, and smoking status.
Statistically non-significant relationship
Choose one characteristic listed in Table 1 that does not show a statistically significant relationship with parenting status. Assume an alpha level of 0.05.
Write an appropriate null and alternative hypothesis test for this chi squared test.
Explain why this relationship NOT is considered statistically significant. Explain how the p value provided supports your reasoning.
Write a conclusion statement to clearly explain the results of this hypothesis test.
Explain in the context of your hypothesis statement what it would mean to make a type II error.
