The IMF declared in June 2022 that "the world's slowest roads are found in the poorest countries--yet another impediment to economic development." They utilized Google Maps to calculate the average time it takes to drive between large cities at least 80 kilometers apart. Your team, as a researcher with another international organization, wants to see if there are any disparities based on continent classifications. Despite the fact that you do not have access to the same data, your team was able to determine that the average permissible speed in urban areas (in kilometers) for a sample of 21 Caribbean countries is 42.57km. It is worth noting that the allowable speed in Caribbean countries varies by 74 km2. Your team leader has requested that you answer the following questions. a) According to the IMF, the world's fastest roads are found in wealthy countries such as Portugal, Saudi Arabia, and Canada. If the average speed in these countries' urban areas is 48.33, use an acceptable inferential method to assess whether the average speed in the Caribbean is significantly lower than that in the affluent economies. Would you agree with the IMF report based on your findings? b) Given your results from a), should you calculate the effect size? Why? If yes, calculate the effect size and interpret your result?
