All you’ll be working on is the Introduction, including the research problem.
Research Question
Is there an inverse association between schooling and years of smoking ?
?Null hypothesis : There is no statistically significant relationship between education level and smoking duration.
Alternative hypothesis: Individuals with higher education levels are more likely with shorter duration of smoking.
These are the sources that will be used.?

COURSE PROJECT
You are required to demonstrate knowledge of PSPPin biostatistics by using data from NHEFS dataset. You are expected to examine the effect of schooling on years of smoking, controlling for
age, race, sex.
Specifically, you should do the following:
1. Provide a title for your project.
2. Provide an introduction, including the research problem
3. State both your research question and the associated null and alternative hypotheses.
4. Include five peer-reviewed articles relevant to your reseach question/hypothesis
5. Run frequency distributions for all the variables in your analysis, and interpret their relevant summary statistics.
6. Use an appropriate statistical model to test the effect of the primary independent variable on the dependent variable, controlling for the other independent variables.
7. Interpret the findings and draw your conclusion.
