- Vanguard's Precious Metals and Mining fund (Metals) and Fidelity's Strategic Income fund (Income) were two top-performing mutuals funds for the years 2000 through 2009. An analysis of annual return data for these two funds provided important information for anytype of investor. Over the past 10 years, the Metals fund posted a mean return of 24.65% with a standard deviation of 37.13%. On the other hand, the mean and the standard deviation of return for the Income fund were 8.51% and 11.07%, repectively. It is reasonable to assume that the returns of the Metals and the Income funds are both normally distributed, where the means and the standard deviations are derived from the 10-year sample period. In a report, use the sample information to compare and contrast the Metals and Income funds from the perspective of an investor whose objective is to 1. Minimize the probability of earning a negative return. 2. Maximize the probability of earning a return between 0% and 10%. 3. Maximize the…Assume that the standard deviation of daily returns for a particular stock in a recent historical period is 1.8 percent. Assume that the expected daily return of the sotck is 0.01 percent. Estimate the maximum possible one-day loss based on a 95 percent confidence level.Consider a population of 1,024 mutual funds that primarily invest in large companies.You have determined that the mean one-year total percentage return achieved by all the funds, is 8.20 and that the standard deviation is 2.75. According to the empirical rule, what percentage of these funds are expected to be within +/- 1standard deviation of the mean? According to the empirical rule, what percentage of these funds are expected to be within +/- 2standard deviations of the mean? According to the Chebyshev rule, what percentage of these funds are expected to be within +/-1, +/-2 or +/- 3 standard deviations of the mean?
- Consider a position consisting of a K200,000 investment in Asset A and a K300,000 investment in Asset B. Assume that the daily volatilities of the assets are 1.5% and 1.8% respectively, and that the coefficient of correlation between their returns is 0.4. What is the five day 95% Value at Risk (VaR) for the portfolio (95% confidence level represents 1.65 standard deviations on the left side of a normal distribution)?The heart rate of 20 patients in the ICU have a mean of 95.3 beats per minute and a standard deviation of 19.6 beats per minute. Are heart rates from the ICU patients unusual given a normal heart rate has a mean of 72 beats per minute? What is the t-stastic?According to the New York Stock Exchange, the mean portfolio value for U.S. senior citizens who are shareholders is $183,000. Suppose a simple random sample of 50 senior citizen shareholders in a certain region of the United States is found to have a mean portfolio value of $198,700, with a standard deviation of $65,000. From these sample results, and using the 0.05 level of significance in a two-tail test, comment on whether the mean portfolio value for all senior citizen shareholders in this region might not be the same as the mean value reported for their counterparts across the nation. Since the observed t-value is _______ than the table value, we would ___ H(0)
- J.P. Morgan Asset Management publishes information about financial investments. Over the past 10 years, the expected return for a core bonds fund was 5.78% with a standard deviation of 2.13%.† J.P. Morgan Asset Management also reported that the expected return for real estate investment trusts (REITs) was 13.07% with a standard deviation of 23.17%. The correlation between core bonds and REITs is −0.04. (Past performance is no guarantee of future results.) You are considering portfolio investments that are composed of a core bonds fund and REITs. a. Using the information provided, determine the covariance between core bonds and REITs. (Round your answers to three decimal places.) covariance = b. Construct a portfolio that is 50% invested in a core bonds fund and 50% invested in REITs. In percentage terms, what are the expected return and standard deviation for such a portfolio? (Round your answer for the standard deviation to two decimal places.) expected return = standard deviation =…Develop a 95% confidence interval for the population slope if the followingregression information are given: b1= 41.7, p-value = 0.02, and n = 35.5. The average cell phone lifespan, according to a new research, is 24.3 months. It takes 2.6 months to reach the standard deviation. Calculate the likelihood that a company's 33 employees will have a mobile phone with a lifespan of less than 23.8 months. Assume that the length of time spent on a mobile phone is a regularly distributed variable
- An analyst is conducting a hypothesis test to determine if the mean time spent on investment research is different from 3 hours per day. The test is performed at the 1% level of significance and uses a random sample of 64 portfolio managers. where the mean time spent on research is found to be 2.7 hours. The population standard deviation is 1.5 hours. What is the value of the test statistic in this case?In the last quarter of 2007, a group of 64 mutual funds had a mean return of 3.4% with a standard deviation of 6.1%. Consider the Normal model N(0.034,0.061) for the returns of these mutual funds. a) What value represents the 40th percentile of these returns? b) What value represents the 99th percentile? c) What's the IQR, or interquartile range, of the quarterly returns for this group of funds?In 2002, the mean age of an inmate on death row was 40.7 years with a standard deviation of 9.6 years according to the U.S. Department of Justice. A sociologist wondered whether the mean age of a death-row inmate has changed since then. She randomly selects 32 death-row inmates and finds that their mean age is 38.9 years. Construct the 95% confidence interval for the current mean age of death-row inmates. A) (34.243, 43.557) B) (36.109, 41.691) C) (34.529, 43.271) D) (35.574, 42.226) E) (35.439, 42.361)
