比較抽樣與自助法的平均數
為了讓計算更容易，這裡提供了與上一題相似的分佈，不過這次的樣本大小是 5000。
已提供 spotify_population、spotify_sample、sampling_distribution 與 bootstrap_distribution；pandas 和 numpy 已以慣用別名載入。

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])
