Question

the average return for large-cap domestic stock funds over the three years 2009–2011 was 14.4% (AAII Journal, February, 2012). Assume the three-year returns were normally distributed across funds with a standard deviation of 4.4%. a. What is the probability an individual large-cap domestic stock fund had a three-year return of at least 20%? b. What is the probability an individual large-cap domestic stock fund had a three-year return of 10% or less? c. How big does the return have to be to put a domestic stock fund in the top 10% for the three-year period?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
