Week 4 Discussion (PHB300 Introduction to Biostatistics)

Choose a public health issue and a disease connected to the issue and briefly design a research study based on other research studies you are using as examples. Include your hypothesis and null hypothesis. Inform us about whether you have a Type 1 or 2 error and explain the relationship between confidence interval estimates and p-values in drawing inferences within your analysis (which you are estimating based on other research studies).
