- A money market mutual fund manages a $ 100 crores fund invested in money market securities. It has assessed its average daily cash needs as 10% of the corpus to meet the redemption pressure even in difficult times. Last 100 days average was found to be 10.08% of the corpus. The experience of mutual fund manager has revealed the standard deviation of average daily cash balance as 30 lakhs $ He wants to find out whether or not his last 100 days average cash balance is within the limits of 10% at a level of significance of 5%. How can you help him ?An investor is trying to decide between 2 mutual funds. Mutual fund #1 offers a slightly higher return than mutual fund #2 so the investor decides that he will invest in mutual fund #1 unless the risk of mutual fund #1 is significantly higher than the risk of mutual fund #2. Using the standard deviation of 101 daily returns as a measure of the risk of the two mutual funds, the investor finds that the standard deviation of mutual fund #1’s daily returns is .81 .95 and the standard deviation of mutual fund #2’s. At the 10% level of significance, should the investor invest in mutual fund #1 or #2?Consider a population of 1024 mutual funds that primarily invest in large companies.
