Beginning with a world map and then proceeding to a regional map, determine the city or feature at each of the following locations: $19^{\circ} 28^{\prime} \mathrm{N}$ latitude, $99^{\circ} 09^{\prime} \mathrm{W}$ longitude: ____. $41^{\circ} 52^{\prime} \mathrm{N}$ latitude, $12^{\circ} 37^{\prime} \mathrm{E}$ longitude: ____. $1^{\circ} 30^{\prime} \mathrm{S}$ latitude, $33^{\circ} 00^{\prime} \mathrm{E}$ longitude: ____

Each boldface number is the value of either a parameter or a statistic. In each case, state which it is. On Tuesday, the bottles of Arizona iced tea filled in a plant were supposed to contain an average of 20 ounces of iced tea. Quality control inspectors sampled 50 bottles at random from the day's production. These bottles contained an average of 19.6 ounces of iced tea.
