The assumption that the outcomes for the treated group and control group are the same is not necessary to build a confidence level for an ATE in an experimental design. In fact, the purpose of conducting an experiment is to see if there is any difference in outcomes between the treatment and control groups. The assumptions required to build a confidence level include having a random sample, randomly assigning treatment, and having a large enough sample size.
