Answer:
32.35% ( the probability that in any given year, the return on long-term corporate bonds will be greater than 10 percent )
Step-by-step explanation:
Given data for long-term corporate bonds
Standard deviation : 8.3%
mean = 6.2%
To calculate the probability that in any given year, the return on long-term corporate bonds will be greater than 10 percent ( USING THE NORM-DIST FUNCTION )
P( x > 10% ) = 1 - P(x<10%) = 1 - NORM-DIST (10,6.2,8.3,TRUE ) = 0.3235
= 32.35%
