Compare sampling and bootstrap means

To make calculation easier, the distributions from the previous exercise have been included in tibbles. mean_popularity_2000_samp is in the sample_mean column of sampling_distribution, and mean_popularity_2000_boot is in the resample_mean column of bootstrap_distribution.

spotify_population, spotify_sample, sampling_distribution, and bootstrap_distribution are available; dplyr is loaded.
