A correlation coefficient of -0.75 indicates a strong negative correlation between the number of hours of sleep and the number of conflicts, which means that as the number of hours of sleep decreases, the number of conflicts increases. Therefore, sleeping too little is associated with more conflicts. Option A and B are incorrect because the correlation coefficient does not provide information about the percentage of conflicts that are related to sleep deprivation or causation. Option D is also incorrect because the correlation coefficient suggests that sleep and conflict are related.
