比较抽样均值与自助法均值
为便于计算，已包含与上一个练习类似的分布，这次使用的样本量为 5000。
已提供 spotify_population、spotify_sample、sampling_distribution 和 bootstrap_distribution；pandas 与 numpy 已按常用别名加载。

交互式实操练习
通过完成这段示例代码来试试这个练习。
# Calculate the population mean popularity
pop_mean = ____
# Calculate the original sample mean popularity
samp_mean = ____
# Calculate the sampling dist'n estimate of mean popularity
samp_distn_mean = ____
# Calculate the bootstrap dist'n estimate of mean popularity
boot_distn_mean = ____
# Print the means
print([pop_mean, samp_mean, samp_distn_mean, boot_distn_mean])
