1. What is the difference between the average change in stock prices in the Nasdaq-100 (or returns)?' Round your answer to 3 decimals: (Hint: This number should be negative because recessions correspond to falling stock prices, slowing GDP growth and reduced consumer spending.) 2.The quantile for a given level q tells us the return such that 9% of the data are smaller than this return. For example, the 99%-quantile (q=0.99) returns the value such that 99% of the data points we are looking at are smaller and only 1% are larger. For the returns of the SPY ETF, find the 85%-quantile by applying the quantile() function to the data frame with the appropriate argument for q. Round your answer to 4 decimals.
