Exercise

Repeated sampling, point estimates and inference

In the previous exercise, you used a single sample of ninety days to make your conclusion. However, what if you had a different ninety days. Would your conclusions be different?

One way to assess this is by taking repeated samples. By repeatedly sampling from your data and computing your point estimate you can see how it changes.

The same data btc_sp_df has been loaded for you, as have the packages Pandas as pd and NumPy as np.
