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

Use appropriate descriptive statistics to summarize each of the three variables for the 40 Gulf View condominiums.
2. Use appropriate descriptive statistics to summarize each of three variables for the 18 No Gulf View condominiums.
3. Compare your summary results. Discuss any specific statistical results that would help a real estate agent understand the condominium market.
4. Develop a 95% confidence interval estimate of the population mean sales price and population mean number of days to sell for Gulf View condominiums. Interpret your results.
5. Develop a 95% confidence interval estimate of the population mean sales price and population mean number of days to sell for No Gulf View condominiums Interpret your results.
6. Assume the branch manager requested estimates of the mean selling price of Gulf View condominiums with a margin of error of $40,000 and the mean selling price of No Gulf View condominiums with a margin of error of $15,000. Using 95% confidence, how large should the sample sizes be?
7. Gulf Real Estate Properties just signed contracts for two new listings: a Gulf View condominium with a list
(e) Is there a significant relationship between the selling price and the assessed value of the house? Use 5 % level of significance.
Compute the population mean margin of error for a 90% confidence interval when sigma is 7 and the sample size is 36.
b. Construct a 91.5% confidence interval for the mean time it take for all workers who are employed in downtown Toronto
AJ DAVIS is a department store chain, which has many credit customers and wants to find out more information about these customers. A sample of 50 credit customers is selected with data collected on the following five variables:
The Written Report must be five pages and graphically display the statistical data developed for three comparable cities, counties, or states. It must incorporate national statistics for comparison. Your assessment may be in bullet or paragraph format below the graphic display.
The information is collected on percent of population that is black and percent of population that is Spanish speaking. The family income is divided by seven classes and the percent of the families in each of the classes, median yearly family income, median home value, median rent per month, percentage of the population with no cars, percentage of

The sales data were obtained for a new oceanside condominium complex consisting of two adjacent and connected eight-floor buildings. The complex contains over 200 units of equal size (approximately 500 square feet each). The
e.) Find a 95% confidence interval for the proportion who stay with D&Y for at least 3 years but this time with starting salaries above the median.
To begin the statistical analysis of the data provided, we need to present the statistical description of it, take a general look at the means and medians for each sector and test the normal distribution of the data to see if we can undertake any further test.
To calculate the mean I added up the sum of days to sell and divided by 18. The mean is 203,188.89, which mean the average of the listed price. The median was calculated by listing the numbers in numerical order from lowest to highest and located the number in the middle of 203,500. The median represents the middle number of the days that it took to sell the condominiums. After calculating the median I located the minimum and maximum based the lowest and highest data, which are 135,500 and 292,500. These represent the range of the sale price. Lastly, I used the formula to get the standard deviation of 43,891.72, which measures the variability.
a) Develop a 99 percent confidence interval for the mean selling price of the home.
The data for the second test to be conducted by our group consists of lot sizes of the residential properties that are up for sale in Toronto and Vancouver. The samples are represented in m2 (metres squared; area of the land in which the residential properties are built on). The data taken are based on the properties that are up for
1 - Produce the relevant descriptive graph and table to summarise the MODE variable (labelled Control: Completes by phone/mail/web). The MODE variable summarises the different ways that each institution completed the survey. Write a paragraph explaining the key features of the data observed through the output.
