Bootstrapping the data
Using the infer
package with type = "bootstrap"
, you can repeatedly sample from the dataset to estimate the sampling distribution and standard error of the slope coefficient. Using the sampling distribution will allow you to directly find a confidence interval for the underlying population slope.

Instrucciones del ejercicio
Use the infer
steps to bootstrap the twins
data 1000 times. You don't have to hypothesize()
because now you're creating confidence intervals, not hypothesis testing!
- Specify
Foster
versusBiological
. - Generate
1000
replicates by bootstrapping. - Calculate the slope statistic.
