Project overview
In this project we study weekly returns from four ETFs AGG VAW IWN and SPY
We load the data with Python and pandas and look at tables histograms and plots over time We describe typical weekly returns and variation for each ETF and we compare them
Then we build confidence intervals for the mean return and use t tests to check if returns differ between ETFs
Finally we write a short report that explains the data the methods and the financial meaning in clear language
