In this scenario, neither random selection nor random assignment is possible or appropriate due to ethical and practical reasons. Random assignment to experimental conditions (e.g., assigning mothers to use cocaine) is unethical. Random selection might not be feasible if the study aims to specifically examine the effects of cocaine use on infants, as it would require a naturally occurring sample of cocaine-using mothers.
