Using the data from Practice Problem 1, state whether each of the following data sets (a through f) is a possible bootstrap replicate sample for use in determining a bootstrap confidence interval for the difference in mean birth weight. If not, explain why.

Data from Practice Problem 1

The following are very small data sets of birth weights (in kg) of either singleton births or individuals born with a twin.

We are interested in the difference in mean weight between singleton babies and twin babies.
