Final answer:
The average return for stock X is 8.24% and the average return for stock Y is 14.16%.
Step-by-step explanation:
To calculate the average returns for stocks X and Y, we sum up the returns for each stock separately over the given years and then divide by the number of years. Here's the step-by-step calculation:
Add the returns for stock X:
22.3% + (-17.3%) + 10.3% + 20.6% + 5.3%
= 41.2%
Divide the sum by the number of years to find the average return for stock X:
41.2% / 5
= 8.24%
Add the returns for stock Y:
27.9% + (-4.3%) + 29.9% + (-15.6%) + 33.9%
= 70.8%
Divide the sum by the number of years to find the average return for stock Y:
70.8% / 5
= 14.16%
Therefore, the average return for stock X is 8.24% and the average return for stock Y is 14.16%.
