Between January and June of 2011, The Gallup survey company conducted telephone interviews. The interviews were part of the Gallup-Healthways Well-Being Index survey. The researchers interviewed a random sample of adults, aged 18 and older. The adults lived in all 50 of the U.S. states and in the District of Columbia. Approximately 500 of the people who were interviewed were men and 500 were women. The people who were interviewed were asked about how much and how often they exercise. The researchers asked these people if they exercise for 30 minutes a day, three or more times each week. Among the women, 47.8% answered “Yes” whereas 54.8% of the men answered “Yes”. The researchers estimated that the 95% confidence interval for the true difference between the proportions of all U.S adult women and men who would answer “Yes” to the question was between -13.2% and -0.82%.

Part 1. Which of the following statements is the best interpretation of the 95% confidence interval?

A. We are 95% confident that, across the United States, men are between 0.82% and 13.2% more likely to exercise for 30 minutes at least 3 times a week than are women.
B. There is between a 0.82% and 13.2% chance that the true percentage of U.S. men who exercise for 30 minutes at least 3 times a week is higher than the percentage of women.
C. We are 95% confident that in the U.S, there are between 0.82% and 13.2% less women exercising for 30 minutes at least 3 times a week than men.

Part 2. Think about the results of the percentage of women and men in the United States who exercise for 30 minutes at least 3 times a week. Which of the following statements are supported by the poll results?

A. There is no difference between the percentage of women and men because both sample percents are close to 50%.
B. There is no difference between the percentage of women and men because the confidence interval includes the -5% level of significance.
C. There is a difference between the percentage of women and men because the sample percentage for women who said “Yes” is below 50%, but above 50% for the sample of men.
D. There is a difference between the percentage of women and men because the confidence interval does not include 0%.

Part 3. Which of the following statements is the best interpretation of the statistical term “95% confidence”?

A. 95% of the time that the same methods are used, the interval estimate will include the true difference between the percentages for women and men in the United States.
B. Adults from 95% of all the states in the United States were included in the poll that was conducted between January and June of 2011.
C. There is a 95% chance that the true percentage of women in the United States who exercise less often than men is between 0.82% and 13.2%.
D. Between 0.82% and 13.2% of the men in 95% of the states in the United States exercised more often than women.

Based on the financial results provided above, complete the excel spreadsheet file provided to you and submit your file in Ilearn. Please include include your name in the filename.

.

Required:

1. Calculate each revenue and expense item as a percentage of total revenues in 2019 and 2018 (show percentages out to TWO decimal places for all revenues and expenses, but round total revenue's percentage to ZERO decimal places- see examples in spreadsheet).

2. Calculate the water sales per customer for 2019 and 2018 (show number out to TWO decimal places- see example in spreadsheet).

3. Calculate the company's budgeted financial performance for 2020 based on the assumptions listed below for each revenue and expense item. Then calculate each item as a percentage of total revenues just like you did for 2019 and 2018. Then calculate the water sales per customer for 2020 just as you did for 2019 and 2018- see examples in spreadsheet.

4. Finally, calculate the differences in each revenue and expense item between 2020 and 2019, and 2019 and 2018- see example in spreadsheet. This will provide you with some insight about the year-to-year changes and help you with your business memo which is the second part of this project.

You must use formulas in the excel spreadsheet rather typing-in calculated numbers to get

full credit. You will also run into rounding errors unless you use formulas. Some formulas

and calculated numbers have already been included in the spreadsheet to help you. YOU

SHOULD HAVE AN ANSWER WHEREVER YOU SEE A QUESTION MARK (?)

ASSUMPTIONS:

Assume that the water company expects that in 2020:

a. The number of customers will increase by 5%.

b. Water sales will increase by 4% and late fees will increase by 1% due to increased customer demand.

c. Hydrant fees will decrease by 1% because several older hydrants will be taken out of service.

d. The cost of water sales will increase by 8% because of higher chemical costs.

e. Payroll expenses will increase by 5.5% due to wage increases and higher medical

insurance expenses.

f. Overhead expense will decrease by 4% because of efforts to reduce costs.

g. Miscellaneous expenses are expected to double because of the purchase of building supplies in anticipation of a major waterline project in 2020.

Here are some check figures to help you out:

2020 Total Revenue=1,409,705

2020 Total Expense=1,602,918

2020 Water Sales per customer= $44.27

Total Income<loss> 2020 vs 2019= <$80,588>

Total Income<loss> 2019 vs 2018=<$496,625>

Total Income <loss> as a percentage of total revenue in 2020=-13.71% Total Income <loss> as a percentage of total revenue in 2019=-8.26%

Your client, Ben McDonald, has written you about his tax situation. Please assume that gross income is $172,900 (which consists only of salary) for purposes of this problem.

December 31, 2016

Dear ***** *****, CPA:

Hi, it’s Ben McDonald again. I understand you need some more information from me in order to complete my tax return. Please let me know what information you need and I’ll be happy to provide it.

I moved this year due to taking a job at SwissLog. The move was in late January and I worked my job at SwissLog for the rest of the year. I moved 650 miles away from my old house but I still live in the same state. I left a little bit early to go on a house-hunting trip that cost me a total of $450. I hired a moving company to move our stuff at a cost of $2,300, and I drove Junior in my car. Junior and I got a hotel room along the way that cost us $65. We spent $35 on meals on the way to our new home. Oh yeah, I took my little boy to a movie on the way and that cost $20.

Can you believe I’m still paying off my student loans, even after 15 years? I paid a total of $900 in interest on my old student loans this year.

Since SwissLog (my employer) never started a retirement plan, I decided I should probably start saving for my golden years. I contributed $3,000 to what the bank referred to as a regular IRA (or was it a REM?). Oh yeah. I also did a little investing this year. I bought a limited partnership interest in IGlow, Ltd. for $10,000. I thought it was going to be a real winner, but this year they took a bath. My portion of the loss was $8,000. Well, at least I did not actually do any work for IGlow, and I get the tax deduction - right?

That should be all the information you need right now. Please calculate my adjusted gross income and complete page 1 of Form 1040. You’re still doing this for free, right?

Sincerely,

Ben

Required: calculate Ben’s AGI and complete the 1st page of the 1040 form (forms can be downloaded from the IRS website).

You have been recruited by a former classmate, Susanna Wu, to join the finance team of a company that she founded recently. The company produces a unique product line of hypoallergenic cosmetics and relies for its success on an aggressive marketing program. The company is in a start-up phase and therefore has no significant history of expenses and revenues upon which to rely for budgeting and planning purposes. Given the restriction on available funds (most of the available capital has been used for new-product development and to recruit a management team), the control of costs, including marketing costs, is thought by the management team to be essential for the short-term viability of the company.

You have held a number of intensive discussions with Susanna and John Thompson, director of marketing for the firm. They have asked you to prepare an estimated budget for marketing expenses for a month of operations.

You are provided with the following data, which represent average actual monthly costs over the past three months:

Cost Amount
Sales commissions $126,500
Sales staff salaries 44,500
Telephone and mailing 56,400
Rental—office building 23,200
Gas (utilities) 12,200
Delivery charges 72,600
Depreciation—office furniture 9,000
Marketing consultants 26,400

Your discussions with John and Susanna indicate the following assumptions and anticipated changes regarding monthly marketing expenses for the coming year:

  • Sales volume, because of aggressive marketing, should increase by 14%.
  • To meet competitive pressures, sales prices are expected to decrease by 7%.
  • Sales commissions are based on a percentage of sales revenue.
  • Sales staff salaries, because of a new hire, will increase by 14%, regardless of sales volume.
  • Because of recent industrywide factors, rates for telephone and mailing costs, as well as delivery charges, are expected to increase by 10%. However, both of these categories of costs are variable with sales volume.
  • Rent on the office building is based on a 2-year lease, with 18 months remaining on the original lease.
  • Gas utility costs are largely independent of changes in sales volume. However, because of industrywide disruptions in supply, these costs are expected to increase by 15%, regardless of changes in sales volume.
  • Depreciation on the office furniture used by members of the sales staff should increase because of new equipment that will be acquired. The planned cost for this equipment is $25,200, which will be depreciated using the straight-line (SL) method, with no salvage value, over a 3-year useful life.
  • Because of competitive pressure, the company plans to increase the cost of marketing consultants by $5,000 per month.

Required:

1. Based on the preceding information, what is the percentage change, by line item and in total, for items in your budget?

2. The management team is worried about the short-term financial position of the new company. Given the strain on available cash, the president has expressed a desire to keep marketing expenses over the next few months to a maximum of $382,000. Discussions with the marketing department indicate that telephone and mailing costs are the only category, in the short run, that can reasonably bear the planned-for reduction in marketing costs. The budget you have prepared includes an assumed 10% increase in telephone and mailing costs. What must this percentage change (positive or negative) be in order to achieve targeted monthly marketing costs? (Hint: The Goal Seek function in Excel can be used to calculate the percentage changes, which can be found under Data, then What-If Analysis.)

Assume the economy has a GDP of $11,500 billion. The unemployment rate is at 7.3% and has been slowly rising for the last 6 months. Inflation was at 2.3% one year ago but has since dropped to near 0%. The MPC in the economy is .80 and the Natural Rate of Unemployment is 4.5%. The target rate for inflation is 2%.

  1. Why would it be better for government to solve the problem using government purchases (part c above) rather than taxes (part d above) to solve the problem?
  2. Assuming that government does decide to use the tax policy, what could happen to cause the policy to be ineffective?

Closing is subject to buyer’s inspection of property by him and his designated specialist and complete satisfaction of specialist with property condition. Aherns’s specialist inspected the property and said he thought the roof would need to be replaced in a few years. He also felt some wood near the front of the cabin should be replaced. Aherns demanded that the Johnsons fix these items or he would not close. The Johnsons maintain they did not agree to any repairs; the condition was for Aherns’ protection so that he could opt out of the agreement. Aherns has threatened to sue for breach of contract. Who should win?
