Finding the mean PROBLEM: Here are the population densities (in number of people per square kilometer) for the seven countries in Central America, along with a dotplot: Population density Country (per km?) Belize 13 Costa Rica 82 El Salvador 292 Guatemala 129 Honduras 67 Nicaragua 44 Panama 44 50 100 150 200 250 300 Population_density_per_sq_km VON (a) Calculate the mean population density for these 7 countries. Show your work. (b) The dotplot above suggests that El Salvador might be an outlier. Ignore El Salvador for a moment and recalculate the mean for the remaining 6 countries. How does this mean compare to the mean you calculated for all 7 countries
