Case Problem1: Bock investment Services
The goal of Bock Investment Services (BJS) is to be the leading money market advisory service in South Carolina. To provide better service for their present clients and to attract new clients, BIS developed a weekly newsletter. BIS is considering adding a new feature to the newsletter that will report the results of a weekly telephone survey of fund managers. To investigate the feasibility of offering this service, and to determine what type of information to include in the newsletter, BIS selected a simple random sample of 45 money market funds. A portion of the data obtained is shown in Table below, which reports fund assets and yields for the past 7 and 30 days. Before calling the money market fund managers to obtain additional data, BIS decided to do some preliminary analysis of the data already collected.
Managerial Report
1. Use appropriate descriptive statistics to summarize the data on assets and yields for the money market funds.
2. Develop a 95% confidence interval estimate of the mean assets, mean 7-day yield, and mean 30-day yield for the population of money market funds. Provide a managerial interpretation of each interval estimate.
3. Discuss the implication of your findings in terms of how BIS could use this type of information in preparing their weekly newsletter.
