Observe how we explicitly set the replace argument to TRUE in order to tell rep_sample_n() that we would like to sample pennies with replacement. Had we not set replace = TRUE, the function would’ve assumed the default value of FALSE and hence done resampling without replacement. Additionally, since we didn’t specify the number of replicates via the reps argument, the function assumes the default of one replicate reps = 1. Lastly, observe also that the size argument is set to match the original sample size of 50 pennies.
