5. Global has never paid a dividend over the past 4 years. Suppose Global's historical prices were as follows: 2019:$52.842020:$61.272021:$57.152022:$65.63 d) Find the 68% and 95% confidence intervals. e) What does the 68% confidence interval tell us? Interpret what this means. b) What is the geometric average of the returns? GeometricMean=[(1+r1)(1+r2)(1+r3)](1/3)1=[(1+0.1595)(1+0.0672)(1+0.1484)](1/3)1=[(1.1595)(0.9328)(1.1484)](1/3)1=[1.2421](1/3)1=[1.0749]1=0.0749 Geometric Mean is 7.49\% c) What is the standard deviation of the returns? a) What is the arithmetic average of the returns? Ret for 2017= [Price of 2017/ Price of 2016] - 1 =[61.27/52.84]1=1.15951=0.1595or15.95% Ret for 2018 = [Price of 2018 / Price of 2017] - 1 =[57.15/61.27]1=0.93281=0.0672or6.72% Ret for 2019= [Price of 2019/Price of 2018] - 1 =[65.63/57.15]1=1.14841=0.1484or14.84% Aver Ret = Snm [ Retl / n
