# 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?

- Zero is not a plausible value for the population slope, one is a plausible value for the population slope.
- Zero is not a plausible value for the estimated slope, one is a plausible value for the estimated slope.
- Zero is a plausible value for the population slope, one is not a plausible value for the population slope.
- Zero is a plausible value for the estimated slope, one not is a plausible value for the estimated slope.
