only answer please 4. A study was conducted using a random sample of women who gave birth between 1998 and 2000. The purpose of thestudy was to quantify the association between post-partum depression and subsequent health outcomes, including beinghomeless for at least some of the time between 2 and 3 years after giving birth. For brevity, this outcome will be referredto as "homeless" in the relevant questions. Of the 375 women who had post-partum depression, 75 were homeless. Ofthe 2,600 women who did not have post-partum depression, 286 were homeless.Consider this study, and other studies comparing outcomes (binary, continuous or time to event) betweenmultiple populations. For such studies, based on random samples from such populations, why do we useconfidence intervals?Confidence intervals guarantee that the study results will be scientifically useful.Confidence intervals account for the uncertainty in sample estimates that comes from the variation in suchestimates across different random studies of the same size.Confidence intervals help validate that a study was well designed.Confidence intervals account for uncertainty that arises because of problems with the study: for example, peopleanswering a question incorrectly, or a broken diagnostic tool.
