A small businessman is planning on opening a new retail location. Three locations are available, and he is interested in the annual income of families near each location. A random sample of 4 families is selected near each location, and the results are shown below (in thousands of dollars). Use this data to test the hypothesis that mean income is the same in all three areas.
| Location 1 | Location 2 | Location 3 |
| 66 | 65 | 71 |
| 65 | 69 | 72 |
| 66 | 63 | 62 |

Fluid Mechanics: A water tank is a cylinder 4 m in height and 2 meters in diameter. The tank is full at time to. The tank sits on a platform 12 m tall. A water tap is located at the bottom center of the tank. The tap, when actuated, opens to a pipe 5 cm in radius.
a. Write down Bernoulli’s equation. Identify the Pressure, Kinetic and Potential Energy terms. Show that each has the units of an energy density (Joules/Volume).
b. Use Bernoulli’s equation to compare the difference in pressure between the surface of the water and the bottom of the tank near the edge? Assume the fluid is motionless near the edge.
c. When a tap is opened water rushes in to a pipe 5 cm in radius. The pipe is straight and drops 12 m to ground level, but along the way slowly in radius to 2 cm. What is the speed of the water as it emerges from the pipe?
d. Use the continuity equation to find the speed of the water as it enters the pipe 12 m above, i.e. bottom of the tank.
e. What is the volume and mass flow rate of the stream of water?
f. What is the pressure of the fluid as it enters the pipe, again at the bottom of the tank.

A positively charged glass rod repels an object suspended by a non-conducting thread. The charge on the object is ____ .
A positive point charge is brought near the outside surface of a neutral conducting sphere and released. The initial position of the point charge is on the positive x axis and the sphere is centred on the origin. The point charge moves in the ____ x direction. (If the point charge does not move, select answer C.)
A negatively charged glass rod attracts an object suspended by a non-conducting thread. The charge on the object is ____ .
A positively charged ball is brought close to a neutral isolated conductor. The conductor is then grounded, while the ball is kept close. If the ground connection is first removed and then the ball is taken away, the conductor has a ____ charge.
Two neutral metal spheres are mounted on insulating supports. They are connected by a wire. A positively charged glass rod is brought near sphere 1. The wire connecting the spheres is removed and the charged rod is then taken away. Now the charge on sphere 1 is ____ .

Lease Classification, Considering Firm Guidance (Issues Memo)
Facts: On 1/1/20X1, Investor, Inc. ("Lessee") signed a Lease Agreement with Developer Inc. ("Landlord") to lease Landlord's newly constructed hotel located at 15 Main St. in San Francisco, CA. The lease term is 20 years, and the estimated life of the building is 40 years. Lessee will occupy all 4 floors of the building. The lease includes renewal options, exercisable at the Landlord's option, to extend the contract term for three additional five-year terms. No purchase option is present in the contract. Lessee's monthly rental payments are $40,000 per month, plus a monthly supplemental rental cost based on Lessee's sales (1% of sales). From experience, Lessee estimates that 1% of its sales should approximate an additional $10,000 per month. As of 1/1/20X1, the appraised value of the building is $15 million. For simplicity, please ignore discounting in this example (use of present value calculations, rates implicit in the lease, etc.). There are no residual value guarantees present.
Assume that this arrangement is within the scope of lease accounting guidance. As needed to clarify areas of judgment, support your response with guidance from both the Codification and from EY's most recent Lease accounting guide book.

Sun City Limited commences construction of a multi-purpose water park on 1 July 2014 for Pretoria Limited. Sun City Limited signs a fixed-price contract for total revenues of $50 million. The project is expected to be completed by the end of 2017 and Pretoria Limited controls the asset throughout the period of construction. The expected cost as at the commencement of construction is $38 million. The estimated costs of a construction project might change throughout the project—in this example, they do change. The following data relates to the project (the financial years end on 30 June): Required (a) Using the above data, compute the gross profit to be recognised for each of the three years, assuming that the outcome of the contract can be reliably estimated. (b) Prepare the journal entries for the 2015 financial year using the percentage-of-completion method. (c) Prepare the journal entries for the 2015 financial year, assuming the stage of completion cannot be reliably assessed.

Eric and Pat are baseball fans. They drove to the local stadium in Eric's car to watch a game, and decided to park in the parking garage. When driving into the parking garage, they were required to take a ticket in order to get access to the garage. The cost for parking the car was $15.00, which was not due until exiting the garage. After taking the ticket, they parked the car and then walked across the street to the game. When the game was over, they walked back to the car. Upon approaching Eric's vehicle, they noticed that one of the windows had been smashed in. Everything inside had been taken, including Pat's work laptop which had been sitting in a bag in the backseat of the car. Eric and Pat were upset that the parking garage security didn't notice and prevent this crime from happening. Eric and Pat filed a lawsuit against the company that runs the parking garage. The company (ABC Co.) defended, stating that on the back of the ticket is a clause which states the following in conspicuous lettering: "ABC Co. is not liable for any loss of contents or damage caused to vehicles parked in the garage due to its own negligence or the actions of any other person." Will the court uphold the clause on the parking ticket? Make sure to fully explain your answer. This means including the law that applies and the reasoning in applying that law.

The economy has been growing at an average rate of 2.5% during the last year. The chairman of the Federal Reserve has stated that due to the economic growth and improvement in the labor markets, as evidenced by a declining unemployment rate, that the Fed stands ready to increase interest rates. Meanwhile, the government is having to deal with a growing budget deficit and may need to borrow money from the public to fund its operations. This is easily done with the sale of Treasury bills and bonds. However, such an increase in borrowing could affect the results of the Fed's actions. Also, any tax reductions that occur will likely affect expenditures by both consumers and businesses. This in turn is expected to increase GDP assuming no surprise events that would negatively affect employment and economic growth.
1. The reaction of the Fed Chairman is that the economic growth during this phase of the economic cycle could produce higher ______
and the Fed's number one goal is for stable ______.
2. The phase of the business cycle given the facts in the statement above implies the economy is not in a ______ phase.
3. The government's increased demand for funds attained from the bond markets implies that as the supply of
bonds ________ holding demand constant, the price will ________ and pushing interest rates _______.
4. If interest rates increase due to the Fed actions, the economic impact is a result of _______ policy.
5. If the Fed does nothing but the government decides to increase bond sales, the resulting impact on interest rates would be a result of _______ policy.
6. Economic variables that predict the near term future condition of the economy are grouped together and called ______ indicators.
7. Unemployment rates exceeding ______ (spell out the value) percent would indicate the economy could be heading towards
a _______.
8. If the economic environment described above continues, business managers could see their cost of labor _______ in the near term if the unemployment rate goes ________, and financing costs further ______ because of anticipated Fed actions. All these events could produce (inflation/deflation) _______ which could in turn cause the business cycle to reach its (peak/trough) ______.
