How big does the return have to be to put a domestic stock fund in the top for the three-year period (to 2 decimals)

20.944%

Explanation:

Complete question is: "The average return for large-cap domestic stock funds over the three years (2009-2011) was 14.8%. Assume the three-year returns were normally distributed across funds with a standard deviation of 4.8%. How big does the return have to be to put a domestic stock fund in the top 10% for the three-year period (to 2 decimals)?"

Top 10% would be 90th percentile.

Z at 0.9 from standard normal table = 1.28

==>> 1.28*4.8% + 14.8%

==>> 6.144% + 14.8%

==>> 20.944%
