Explanation / Answer

1. As given in the problem introduction, the ticker symbol of the stock prices for the given data is 'AMZN'.

2. It is pretty clear from the table that the number of observations for closing prices (from Aug 8-Aug 19) is 10.

3. Sum of the closed prices:

757.31+764.46+764.63+764.04+768.49+772.56+771.24+768.56+768.31+766.56 = 7666.16

4. Sum of squares of the closed prices:

(757.31)^2+ (764.46)^2+(764.63)^2+(764.04)^2+(768.49)^2+(772.56)^2+(771.24)^2+(768.56)^2+(768.31)^2+ (766.56)^2 = 5877169.6208
