a. What percentage of western states would you expect to have property crime rates between 2602 and 4060?
b. What percentage of western states would you expect to have property crime rates between 1873 and 4789?
c. If someone guessed that the property crime rate in one western state was 9000, would you agree that that number was consistent with this data set?
