Clearly, homeowners who outfit their homes with burglar alarms are more likely to become victims of burglary than are homeowners who do not.
The conclusion above depends on which of the following assumptions?
A. The number of homes that were burglarized within the last five years is greater than the number of homes equipped with burglar alarms. B. A significant number of the homes that were burglarized within the last five years were burglarized more than once within this time period. C. Homes that have been burglarized within the last five years are more likely to be burglarized than are homes that have not been burglarized within the last five years. D. Homeowners who outfit their homes with burglar alarms are less likely to become victims of burglary than are homeowners who have not installed such alarms. E. Homeowners in Stockton who have outfitted their homes with burglar alarms are more likely to be victims of burglary than homeowners with burglar alarms living in other similar cities.
