5.32 I am considering two alternative investments. In both cases I am unsure about the percentage return but believe that my uncertainty can be represented by normal distributions with the means and standard deviations shown in the accompanying table. I want to make the investment that is more likely to produce a return of at least 10%. Which investment should I choose?

Mean Standard Deviation Investment A 10.4 1.2 Investment B 11.0 4.0
