PLEASE QUOTE ALL SOURCES AND DO NOT COPY AND PASTE! _______________________________________________________ Chance and Peter are soon to celebrate their 5th wedding anniversary. They have a couple of very specific financial goals - one is to celebrate their wedding anniversary with a return trip to Europe. The other is to buy their first home later this year (2011). Their combined gross income is $100,000. Overall, approximately 40% of their gross pay is deducted to cover federal and provincial taxes, along with employment benefits. From their disposable income, they set aside $500 monthly in RRSP contributions and pay approximately $1,000 a month for rent, electricity and heating. They also make payments against their debt which is structured as follows: ? Chance borrowed $10,000 on a line of credit 12 months ago to purchase a used car. She is required to reduce the balance of the loan by 1% per month, along with paying the monthly interest of 0.5%. ? Peter transferred a $20,000 balance owing on his educational line of credit to an installment loan charging 9% per annum, compounded monthly 2 three years ago. He has made regular monthly payments since then. The original term of the loan was 10 years. The couple manages their cash flows very closely. In addition to the $20,000 combined balance of their RRSPs, they have $15,000 in a TFSA deposit and $10,000 in a self-directed non-registered investment account. Aside from $3,000 they have earmarked for their anniversary trip, they would be willing to liquidate both the TFSA and investment account to make a down payment on a home. This would be in addition to the maximum withdrawal under the Home Buyers' Plan. Question 1 (10 marks) What is the balance of Chance's line of credit and Peter's education loan? Please show all calculations. Question 2 (10 marks) Assume that their financial institution applies a GDS of 30% (excluding heating and insurance) and a TDS of 40% (excluding heating and insurance). Given an estimated $300 in property taxes, what is the most they could pay each month for a mortgage use both ratios? Presume the mortgage term would be 25 years and charge 0.45% per month in interest. (Hint: Calculate next month's charge for Chance's line of credit and use this amount to estimate her required monthly debt payment.) Question 3 (35 marks) Chance and Peter are looking at homes in St-Basile-le-Grand. In this community, the average home is $250,000 with property taxes of approximately $300 a month. If they take out the maximum loan under the Home Buyers' Plan and empty their TFSAs and investment account except for their vacation funds, what will be the monthly cost of a home in 2012 and 2013? Make the following assumptions to simplify your analysis. (Research is required - please state your sources.) ? They will opt for a 25-year mortgage at a 0.45% monthly rate of interest. ? Home acquisition costs, excluding the land transfer tax, will amount to $10,000. 3 ? They will pay the land transfer tax and home acquisition costs outright, but will add the cost of insuring their mortgage with CMHC to the balance of their loan. ? They will make the minimum legal repayments to the Home Buyers' Plan when required. ? Their home insurance will be $60 a month, up $30 from the cost of their tenants' package. ? The First Time Home Buyers' federal tax credit will be received monthly in 2012. ? Their heating and utilities will amount to $200 a month. Question 4 (15 marks) In your estimation, would they be able to afford the home under the terms described? Please support your answer with calculations and refer to the GDS ratio, TDS ratio and their monthly cash flow. With respect to the latter, calculate how much they would have available each month for variable expenses currently, as tenants, and as homeowners. Question 5 (10 marks) Identify two major omissions in their analysis. Please explain. Question 6 (20 marks) The couple's home insurance costs will rise. Explain the meaning of each of the following, and how the couple can overcome the restriction that it creates. ? Named perils ? Co-insurance clause of 80% and escalating replacement costs ? High premium cost due to low deductible of $500 ? Cap on insurance coverage for electronic equipment

Question 5

You asked: "Fowle Marketing Research, Inc., bases charges to a client on the assumption that telephone surveys can be completed in a mean time of 15 minutes or less. If a longer mean survey time is necessary, a premium rate is charged. Suppose a sample of 35 surveys shows a sample mean of 17 minutes. Use = 4 minutes. Is the premium rate justified? a. Formulate the null and alternative hypotheses for this application. H0: Ha: b. Compute the value of the test statistic (to 2 decimals). c. What is the p-value (to 4 decimals)? d. Using = .01, is a premium rate justified for this client? Nielsen reported that young men in the United States watch 56.2 minutes of prime-time TV daily (The Wall Street Journal Europe, November 18, 2003). A researcher believes that young men in Germany spend more time watching prime-time TV. A sample of German young men will be selected by the researcher and the time they spend watching TV in one day will be recorded. The sample results will be used to test the following null and alternative hypotheses. H0: less than or equal to 56.2 Ha: greater than 56.2 a. In this situation, a Type I error would occur if it was concluded that the population mean prime-time TV viewing for young men in Germany was minutes per day when in fact it was not. b. In this situation, a Type II error would occur if it was concluded that the population mean prime-time TV viewing for young men in Germany was minutes per day when in fact it was not The Employment and Training Administration reported the U.S. mean unemployment insurance benefit of $238 per week (The World Almanac 2003). A researcher in the state of Virginia anticipated that sample data would show evidence that the mean weekly unemployment insurance benefit in Virginia was below the national level. a. Develop appropriate hypotheses such that rejection of H0 will support the researcher's contention. H0: Ha: b. For a sample of 110 individuals, the sample mean weekly unemployment insurance benefit was $231 with a sample standard deviation of $90. The p-value is c. Using = .05, can you conclude that the mean weekly unemployment insurance benefit in Virginia is below the national level? Answer the next three questions using the critical value approach. d.

Raftelis Financial Consulting reported that the mean quarterly water bill in the United States is $47.50 (U.S. News && World Report, August 12, 2002). Some water systems are operated by public utilities, whereas other water systems are operated by private companies. An economist pointed out that privatization does not equal competition and that monopoly powers provided to public utilities are now being transferred to private companies. The concern is that consumers end up paying higher-than-average rates for water provided by private companies. The water system for Atlanta, Georgia, is provided by a private company. A sample of 64 Atlanta consumers showed a mean quarterly water bill of $51 with a sample standard deviation of $12. At = .05, does the Atlanta sample support the conclusion that above-average rates exist for this private water system? a. State your hypotheses. H0: Ha: b. What is the t statistic (to 2 decimals)? c.

Compute the value of the test statistic (to 2 decimals). b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value. The p-value is Answer the next three questions using the critical value approach. c. Using = .05, what is the critical value for the test statistic? d. State the rejection rule: Reject H0 if t is the critical value. e. Using = .05, can you conclude that the population mean is greater than 12? Wall Street securities firms paid out record year-end bonuses of $125,500 per employee for 2005 (Fortune, February 6, 2006). Suppose we would like to take a sample of employees at the Jones & Ryan securities firm to see whether the mean year-end bonus is different from the reported mean of $125,500 for the population. a.

A study found that, in 2005, 12.5% of U.S. workers belonged to unions (The Wall Street Journal, January 21, 2006). Suppose a sample of 390 U.S. workers is collected in 2006 to determine whether union efforts to organize have increased union membership. a. Formulate the hypotheses that can be used to determine whether union membership increased in 2006. H0: p Ha: p b. If the sample results show that 50 of the workers belonged to unions, what is the sample proportion of workers belonging to unions (to 2 decimals)? c. Complete the following, assuming an level of .05. Compute the value of the test statistic (to 2 decimals). What is the p-value (to 4 decimals)? What is your conclusion?
