7.3 Fill in the spreadsheet below to calculate the port- folio return and risk between Zenon and Dynamics, given the 10 years of annual returns for each stock and portfolio weights of 50/50. (a) How would your answer change if the weights were 40 percent for Zenon and 60 percent for Dynamics? (b) How would your answer change if the weights were 30 percent for Zenon and 70 percent for Dynamics? Expected return Variance Standard deviation Covariance Weight for Zenon Weight for Dynamics Expected portfolio return Portfolio variance Portfolio standard deviation Zenon Return (%) 9.89 -12.34 13.56 34.56 -15.23 20.09 7.56 16.47 18.34 15.56 Zenon Dynamics 50% 50% Dynamics Return (%) -47.67 30.79 24.78 7.89 24.42 34.56 67.56 44.67 78.56 51.00 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 a. Simulate the predator-prey model (the Lotka-Volterra model) with the following parameters and visualize the simulated dynamics. (3 points) k1=0.13, k2=0.01, k3=0.2, f-0.2, NO=80, and P0=20 b. Based on the simulation result you observed in Problem 2a, what is the maximum population size of the prey species? Type your answer in the text cell below. (2 points) Using R in google collab.
