Answer:
26.5, 14.344
Step-by-step explanation:
given that you find a certain stock that had returns of 9 percent, −16 percent, 18 percent, and 14 percent for four of the last five years. The average return of the stock over this period was 10.3 percent,
Let the missing return in the 5 years be x
Then we get total of all five years
= 
This will also be equal to the given average multiplied by 5
= 
Equate both to get an equation in X as

Missing year return =26.5
Variance = sum of (x-10.3)^2
=
Std dev= 14.344
