In an article published in Sustainability (Vol. 12, 2020), a group of researchers sought to identify an appropriate forecasting method to reduce the number of road accidents in Thailand. The data used in the analysis included the death rate per 100,000 citizens, gross domestic product (GDP), number of registered vehicles (motorcycles, cars, and trucks), and energy consumption of the transportation sector. Let y = death rate and x = number of registered cars. The researchers assumed that the death rate increases as the number of registered cars increases. After the analysis, the model yielded an estimated slope of -.120, with an associated two-tailed p-value of .05. Do you agree with the researchers’ assumption?
