Abstract

There are close to 1.2 million career and volunteer firefighters across the United States. In the year 2020 alone 62 of these firefighters died and 64,875 were injured. The following research was performed to determine if the firefighter profession has become safer due to new standards and regulations. Each year the National Fire Protection Agency(NFPA) and the Federal Emergency Management Agency(FEMA) collect data on the number of firefighter deaths and injuries, in order to determine if the standards and regulations are keeping firefighters safe. Statistical hypothesis testing and linear regression were performed on the data to show if in fact the profession is safer. This paper seeks to prove using a t-distribution hypothesis test on the correlation coefficient and the slope parameter, that over the last 40 years there has been a significant decrease in career and volunteer firefighter deaths and injuries.
