what would the randomization be here for a hypothesis test? Researchers reported a study where 48 cocaine abusers were randomly assigned to receive one of two treatments for six weeks: 24 subjects received the antidepressant drug desipramine hydrochloride and the remaining 24 subjects received lithium carbonate, the standard treatment. For those that received desipramine hydrochloride, 41.7% lapsed during the six-week period. For those that received lithium carbonate, 75% lapsed during the six-week period. Perform a hypothesis test to determine if the probability of having a relapse is lower for desipramine hydrochloride than lithium carbonate. Use a significance level of 0.05
