Inference from randomization and bootstrapped distributions

Throughout this chapter we have investigated the slope associated with the regression of Foster twins on Biological twins. The inference question was based on a randomization test assuming no relationship between the two types of twins (i.e., a slope of zero). The confidence intervals investigated a research question associated with a 100% nature relationship (i.e., a slope of one). What are the appropriate conclusions of this study?
