Compare sampling and bootstrap standard deviations
In the same way that you looked at how the sampling distribution and bootstrap distribution could be used to estimate the population mean, you'll now take a look at how they can be used to estimate variation, or more specifically, the standard deviation, in the population.
Recall that the sample size is 5000.
spotify_population, spotify_sample, sampling_distribution, and bootstrap_distribution are available; pandas and numpy are loaded with their usual aliases.
