1. Please use STATA for the following analysis and please provide the STATA syntax. In this question, we will estimate a model of life expectancy at birth across the 50 states and the District of Columbia using median income. The data is following. You must complete the following tasks. Use 5% level of significance for the estimation. (1) Clearly propose and identify the model specification you would like to estimate. You may use appropriate data visualization tools to help you identify the specification. Please provide your reasoning. You will need to find supporting articles in the literature for your reasoning. Relevant articles can be easily found online and downloaded through our library (e.g. JSTOR). Please provide a clear quotation and list of references. (2) Estimate the model in (1) using the data below. Explain your findings? Does the estimated coefficient fit with your expectations from the literature?
