The expected value for all three years is $80.
Compute the standard deviation for each of the three years.
(Do not round intermediate calculations. Round your answer
to 2 decimal places.)
Solution :

= 13.42 % ( when rounded off to two decimal places )
Standard Deviation for Year 5 = 25.0998 %
= 25.10 % ( when rounded off to two decimal places )
Standard Deviation for Year 10 = 30.9839 %
= 30.98 % ( when rounded off to two decimal places )
