1. Multiple Regression Analysis Part 2[5 points]

This part of the exam is based on the article, "A Comprehensive Analysis of COVID-19 Transmission and Mortality Rates at the County Level in the United States Considering Socio-demographics, Health Indicators, Mobility Trends, and Health Care Infrastructure Attributes," which was published two years ago in PLOS One. It further tests your understanding of multiple regression analyses as applied in current social and policy problems. Download a PDF copy of the journal article and focus on Table 2 (Estimation Results for Daily COVID-19 Transmission Rate per 100K Population).

Take a look at the Mobility variables. From Table 2, what is the impact of staying at home on COVID-19 transmission? Is this effect positive or negative? What does that mean? Secondly, is this impact or outcome statistically significant? Why or why not?

Finally, what policy implications or recommendations can you derive from this multiple regression analysis.
