SIGNIFICANT DIFFERENCE INFERENTIAL STATISTICS

Full Answer Section

Rationale for Choosing a T-test or ANOVA

• T-test: If you are comparing the economic costs between two groups (e.g., high vs. low socioeconomic status), a t-test would be appropriate.
• ANOVA: If you are comparing costs among more than two groups (e.g., multiple racial/ethnic groups), an ANOVA would be more suitable.

Note: The specific choice of t-test or ANOVA would depend on the assumptions of normality and homogeneity of variance.

Additional Research Questions and Hypotheses

Based on the problem statement and purpose statement, you could also consider exploring other research questions and hypotheses related to:

• Prevalence of SLE:
  • H0: There is no significant difference in the prevalence of SLE among different racial/ethnic and socioeconomic groups.
  • H1: Individuals from lower socioeconomic status and racial/ethnic minority groups will have a higher prevalence of SLE.
• Disease Manifestations:
  • H0: There is no significant difference in the severity and organ involvement of SLE among different racial/ethnic and socioeconomic groups.
  • H1: Individuals from lower socioeconomic status and racial/ethnic minority groups will experience more severe SLE manifestations and organ damage.
• Access to Care:
  • H0: There is no significant difference in access to specialized care, available treatments, and medication adherence among different racial/ethnic and socioeconomic groups.
  • H1: Individuals from lower socioeconomic status and racial/ethnic minority groups will have limited access to specialized care, fewer treatment options, and lower medication adherence.

By addressing these research questions and testing the corresponding hypotheses, you can provide valuable insights into the disparities in SLE outcomes and inform efforts to improve healthcare equity.

Sample Solution

Does socioeconomic status and race/ethnicity influence the direct and indirect economic costs associated with SLE?

Hypotheses

Null Hypothesis (H0): There is no significant difference in direct and indirect economic costs associated with SLE among different racial/ethnic and socioeconomic groups.

Alternative Hypothesis (H1): Individuals from lower socioeconomic status and racial/ethnic minority groups will experience higher direct and indirect economic costs associated with SLE compared to more affluent, non-minority populations.
