An insurance company is interested in estimating the population mean cost of basic dental

cleaning at dentists in Saskatoon. Suppose there are only two dentists in Saskatoon:

Dentist A and Dentist B. Suppose also that the cost of basic dental cleaning varies only

depending on how well the patient practices regular dental hygiene, so that the cost of

basic dental cleaning roughly follows a Normal distribution regardless of the dentist.

The insurance company selects 8 sample patients and sends them to both Dentist A and

Dentist B. They send the patients in random order, such that half of the patients are seen

by Dentist A first, and half are seen by Dentist B first, so as not to bias the results. The

cost of basic dental cleaning for these 8 patients seen by both Dentists A and B are

provided below. The insurance company would like to determine whether the population

mean cost of basic dental cleaning by Dentist A is different from the population mean

cost of basic dental care by Dentist B. Let the population of costs of basic dental care

from Dentist A be population 1.

Patient 1 2 3 4 5 6 7 8

Dentist A $100 $120 $125 $110 $95 $105 $120 $115

Dentist B $150 $100 $140 $100 $95 $105 $100 $120

 Looner Industries is currently analyzing the purchase of a new machine that costs $ 159,000 and requires $ 19,500 in installation costs. Purchase of this machine is expected to result in an increase in net working capital of $ 29,800 to support the expanded level of operations. The firm plans to depreciate the machine under MACRS using a​ 5-year recovery period​

and expects to sell the machine to net $ 9,700 before taxes at the end of its usable life. The firm is subject to a 40 % tax rate.

a. Calculate the terminal cash flow for a usable life of ​ (1) 3​ years, (2) 5​ years, and​ (3) 7 years.

b. Discuss the effect of usable life on terminal cash flows using your findings in part a.

c.  Assuming a​ 5-year usable​ life, calculate the terminal cash flow if the machine were sold to net​ (1) $ 8,925 or​ (2) $ 169,300 ​(before taxes) at the end of 5 years. d. Discuss the effect of sale price on terminal cash flow using your findings in part c. a. Calculate the terminal cash flow for a usable life of ​ (1) 3​ years, (2) 5​ years, and​ (3) 7 years. The following table can be used to solve for the terminal cash​ flow:  ​(Round to the nearest​ dollar.) 3-year Proceeds from sale of proposed asset $ +/- Tax on sale of proposed asset $ Total after-tax proceeds-new $ + Change in net working capital $ Terminal cash flow $

Helene Maxwell was a 65-year-old woman who lived alone. Her husband had passed away 12 years ago after an automobile accident, and she had one daughter, who was actively serving in the military overseas, stationed in Iraq. She awoke on a Monday morning not feeling well. She was a bit nauseated with severe heartburn. She had taken an antacid with no relief, and the pain grew worse. Helene had no history of cardiac trouble and was the picture of health for her age, ate right, never smoked, and walked two miles every day, so she did not suspect she was having a heart attack. Eventually, Helene began to feel dizzy and called her physician, Dr. Tondra Washington. Dr. Washington’s nurse spoke with Helene and directed her to call 911 immediately.

Helene followed the order to call for help and was transported to Middletown General Hospital. During her initial interview with the nursing staff in the Emergency Department, she indicated that she had a living will and a do not resuscitate order on record at Middletown General from an observation visit three months ago. Helene told the nurse that she had numerous hospitalizations, both inpatient and outpatient, over the past 10 years. Dr. Washington arrived at the emergency room and requested prior records.

Mondays are always very busy in the Health Information Services department at Middletown General Hospital. The call for Helene Maxwell’s records was received by Rachelle, who had been with Middletown General for 15 years. It was a routine request for records that appeared, in the computer, to be incomplete and should have been filed in the incomplete record file room. There were deficiencies for two physicians, neither of whom had recently been in to complete their records.

When Rachelle was unable to locate the records in the incomplete file area, she checked the dictating areas, the permanent records room, and areas with charts pulled for studies, and she still had no luck in locating the record. While she was searching, Robert answered a call from the Emergency Department, stating that they needed Mrs. Maxwell’s records immediately because they needed the living will and the order for do not resuscitate. Robert began to help Rachelle in the search for the records. They searched the entire department and enlisted the help of other members of the Health Information Services team. Nobody was having any luck, and Dr. Washington came to the department, abruptly stating the urgency of the situation. She had checked with her office staff, and Mrs. Washington had never given them copies of the living will and the do not resuscitate order, so the only known available copy was the one in her hospital records.

Rachelle went to get Marvin, Director of Health Information Services, from an administrative meeting so that he would be aware of the situation and hopefully provide suggestions of additional options to locate the lost record. Meanwhile, Helene Maxwell went into cardiac arrest, and cardiopulmonary resuscitation was initiated because there was not any available documentation to direct otherwise. Helene was intubated and transferred to the intensive care unit with mechanical ventilation.

Dr. Washington had the nursing staff initiate the process to find out how to contact Mrs. Maxwell’s daughter, Sarah, in Iraq. She told the nurses that once contact with Sarah was established, she would like to personally talk to her because of the nature of the situation. Eventually, Sarah was located, informed regarding her mother’s condition, and plans were in place for her to come home on leave.

When Sarah got home, she searched her mother’s house for the original documents and was unsuccessful. She had no idea who her mother’s attorney was or whether she had even gone through an attorney to complete the documents. Sarah was upset about the hospital not being able to locate her mother’s chart with the do not resuscitate order and living will. By the time she had arrived, Mrs. Maxwell had a feeding tube inserted and was not functioning at all on her own. Sarah was faced with a difficult decision and had no idea what her mother’s wishes were in the living will.

DeLong Corporation was organized on January 1, 2020. It is authorized to issue 10,000 shares of 8%, $100 par value preferred stock, and 500,000 shares of no-par common stock with a stated value of $2 per share. The following stock transactions were completed during the first year.

1. Financial institutions in the U.S. economy

Suppose Nick would like to invest $9,000 of his savings.

One way of investing is to purchase stock or bonds from a private company.

Suppose TouchTech, a hand-held computing firm, is selling stocks to raise money for a new lab—a practice known as finance. Buying a share of TouchTech stock would give Nick the firm. In the event that TouchTech runs into financial difficulty, will be paid first.

Suppose Nick decides to buy 100 shares of TouchTech stock.

Which of the following statements are correct? Check all that apply.

The price of his shares will rise if TouchTech issues additional shares of stock.

An increase in the perceived profitability of TouchTech will likely cause the value of Nick's shares to rise.

The Dow Jones Industrial Average is an example of a stock exchange where he can purchase TouchTech stock.

Alternatively, Nick could invest by purchasing bonds issued by the U.S. government.

Assuming that everything else is equal, a municipal bond issued by a state most likely pays a   interest rate than a corporate bond issued by an electronics manufacturer.
