Question 14 Another researcher also used population density ratings and number of years of experience of police officers to predict incidents of "friendly fire." She found that, for her sample, the partial slope coefficient associated with population density was 0.99 and the partial slope coefficient associated with years of experience of police officers was -0.97. How should she explain the meaning of her partial slope coefficients? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a Population density and years of experience in policing contribute equally but in opposite directions towards changes in the number of friendly fire incidents. b The relationships between population density and years of experience in policing are not significantly different in their contribution to changes in the number of years of experience in policing. C For every one point increase in the population density rating, there was about one additional incident of friendly fire while for every additional year of policing experience, there was about one less incident of friendly fire. d There is a statistically significant positive relationship between population density and incidents of friendly fire and a statistically significant negative relationship between years of policing and incidents of friendly fire.
