a. Average Return of Stock A =(-15%+24.25%+15.75%-2%+23.75%)/5 =9.35%
Average Return of Stock B =(-15.80%+24.90%+22.90%-7.60%+22.35%)/5 =9.35%

b. In Year 2011 Average return =50%*-15%+50%*-15.80% =-15.40%
In Year 2012 Average return =50%*24.25%+50%*24.90% =24.575% or 24.58%
In Year 2013 Average return =50%*15.75%+50%*22.90% =19.325% or 19.33%
In Year 2014 Average return =50%*-2%+50%*-7.60% =-4.80% or -4.80%
In Year 2015 Average return =50%*23.75%+50%*22.35% =23.05%
average return of Portfolio =(-15.40%+24.575%+19.325%-4.80%+23.05%)/5 =9.35%

c. Standard Deviation of Stock A =(((-15%-9.35%)^2+(24.25%-9.35%)^2+(15.75%-9.35%)^2+(-2%-9.35%)^2+(23.75%-9.35%)^2)/(5-1))^0.5=17.26%
Standard Deviation of Stock A =(((-15.80%-9.35%)^2+(24.90%-9.35%)^2+(22.90%-9.35%)^2+(-7.60%-9.35%)^2+(22.35%-9.35%)^2)/(5-1))^0.5=19.46%

Standard Deviation of Portfolio =(((-15.40%-12.34%)^2+(24.575%-12.34%)^2+(19.325%-12.34%)^2+(-4.80%-12.34%)^2+(23.05%-12.34%)^2)/(5-1))^0.5 =18.25%
