A clinical trial was conducted using a new method designed to increase the probability of conceiving a boy. As of this​ writing, 297 babies were born to parents using the new​ method, and 241 of them were boys. Use a 0.01 significance level to test the claim that the new method is effective in increasing the likelihood that a baby will be a boy. Identify the null​ hypothesis, alternative​ hypothesis, test​ statistic, P-value, conclusion about the null​ hypothesis, and final conclusion that addresses the original claim. Use the​ P-value method and the normal distribution as an approximation to the binomial distribution.

An 11-year-old boy presents to the emergency room (ER) with a 4-inch laceration on his right arm. He was with his friends doing bicycle stunts when he fell off his bike and cut his arm on a rusty nail from the ramp. In addition, his wrist is swollen, bruised, tender to touch, and warm, with limited mobility. He will most likely need stitches to close the laceration and a splint for the sprain.

In your initial post answer the following questions:

1. After treatment, as he prepares to leave, you give him last-minute care instructions for laceration and sprain. What would be important for this boy to know to prevent further health concerns with his injuries?
2. The boy concernedly asks you, “My uncle lost his foot because he got gangrene in it. Am I going to lose my arm if I get an infection in this cut?” How would you respond?

What is the overall point of the graphic that showed that market share = product position x marketing effort?

Perform a written and graphic analysis of the relationship between capital, investment demand and savings supply. In your analysis present the different movements of investment demand and savings supply. That is, an increase in the demand for investment and a contraction in the demand for investment, versus an increase in the supply of savings and a contraction in the supply of savings, with the macroeconomic equilibrium.

The data in the table below gives sales revenue for Continental Divide Mining from 1995 to 2005.

YEAR YEARS SINCE 1990 SALES REVENUE (MILLIONS)
1995 2.6155
1998 3.3131
1999 3.9769
2000 4.5494
2001 4.8949
2002 5.1686
2003 4.9593
2005 4.7489

(a) Complete the missing column in the table.
(b) Use Excel to determine the quadratic regression model, y, that best represents sales revenue as a
function of, x, the number of years since 1990. Round three decimal places.

(a) Find the year in which there is maximum revenue and find the maximum revenue. Write solution as a

1. On January I , 2008 Opko Printing Company purchased a new printing press for $80,000 with an estimated residual value of $8,000. It depreciates the press over a five year period using the declining balance method of depreciation. (a) The depreciation expense for Dec. 31 2012 is

On January 1, 2018, Hobart Mfg. Co. purchased a drill press at a cost of $39,300. The drill press is expected to last 10 years and has a residual value of $6,300. During its 10-year life, the equipment is expected to produce 500,000 units of product. In 2018 and 2019, 26,500 and 87,000 units, respectively, were produced. Required: Compute depreciation for 2018 and 2019 and the book value of the drill press at December 31, 2018 and 2019, assuming the units-of-production method is used. (Round depreciation per unit to 2 decimal places.)

Warmack Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $550,000 is estimated to result in $230,000 in annual pretax cost savings. The press falls in the MACRS five-year class, and it will have a salvage value at the end of the project of $93,000. The press also requires an initial investment in spare parts inventory of $28,000, along with an additional $3,300 in inventory for each succeeding year of the project. The shop’s tax rate is 34 percent and its discount rate is 9 percent. MACRS schedule Calculate the NPV of this project.
