Question
A study was done to determine whether the amount of money spent on soft drinks was related to mortality from diabetes. The investigators collected data on per capita (average per person) soft drink consumption in 10 U.S. states and examined its relationship to mortality rates from diabetes in those 10 states. In order to calculate per capita sales, they gathered annual data on soft drink sales from commerce records and then divided these figures by the state's population from the most recent Census. The mortality data were gathered from the vital records department in each state. Here are the data that they collected.
