Null Hypothesis: There is no association between race and ethnicity and coronary heart disease.

Alternate Hypothesis: There is an association between race and ethnicity and coronary heart disease.

Statistical Test: To be determined.

Methods

The study seeks to determine whether there is a significant association between ones race and their risk of getting coronary heart disease. The target population is adults (aged 18 and over) living in the United States. The study participants are adults admitted to US community hospitals, including general, short-term, non-federal, and other specialty hospitals, for diverse health-related complications between 2019 and 2020. The researcher will conduct a retrospective analysis of secondary data obtained from the National Inpatient Sample (NIS) for years 2019 to 2020. The NIS is the largest inpatient care database in the US, which incorporates all payers and draws from state inpatient databases to cover over 7 million in-patient hospital stays across 48...

This makes the data highly representative of the US populations public health status.

…(Black), 3 (Hispanic), 4(Asian or Pacific Islander), 5(Native American), and 6 (Other). Invalid responses will be eliminated from the study. Simple linear regression will be used to test the strength of the association, or how well race predicts the risk of coronary heart disease. Linear regression is appropriate when the dependent variable is continuous in nature, while the independent variable is either continuous or categorical as is the case with the variables in this study. The variable race will be coded as a dummy variable in the regression, in which case non-weighted numerical values will be assigned to represent different racial…
