Two substance abuse clinics would like to compare retention rates for the programs offered by each to see whether the proportion of clients who stayed in after 90 days is different for the two clinics. A simple random sample of clients from each clinic is taken, recording whether the client was still in the program after 90 days. Clinic B has more clients and was able to collect a larger sample. The results of the sample are shown below. What are the population parameters? ✓ Pick The difference in the sample sizes The difference in the two sample means Succ Obse Prop Confi Z-score p-value The proportion of all clients for each clinic that remained in the programs after 90 days The proportion of clients for each sample that remained in the programs after 90 days The alternative hypothesis aPA FICK PB 2.178 0.029 Should Ho be rejected or does Ho fail to be rejected? Pick What conclusion can be drawn from the data? Pick evidence exists to support the claim that retention rates for the two clinics are different.
