Q1) Consider population of 1,024 mutual funds which mainly invested in companies. It is determined that m, mean one-year total percentage return achieved by all funds, is 8.20 and s, standard deviation, is 2.75. Additionally, assume it is determined that range in one-year total return is from -2.0 to 17.1 and that quartiles are, respectively, 5.5(Q1) and 10.5(Q3). According to empirical rule, what percentage of these funds is expected to be
i) Within ±1 standard deviation of mean?
ii) Within ±2 standard deviation of mean?
iii) According to Bienayme-Chebyshev rule, what percentages of these funds are likely to be within ±1 standard deviation of mean?
iv) According to Bienayme-Chebyshev rule, what percentages of these funds are likely to be within ±2 standard deviation of mean?
v) According to Bienayme-Chebyshev rule, what percentages of these funds are likely to be within ±3standard deviation of mean?
vi) According to Bienayme-Chebyshev rule, at least 93.75% of these funds are likely to have one-year total returns between what two amounts?
