Sample of n=5 scores has a mean of M =12. If one person with a score of x=8 is removed from the sample, what will be the value for the new mean? Solution M=12 n=5 Total score=12*5=60. If one person with x=8 is removed then the new total is:-> New Total= 60-8=52 The new mean is:-> n(new)=5-1=4 M(new)= 52/4=13..

Scenario 16-4 Consider the problem facing two firms, Burger Prince and McDaniel\'s, in the fast-food restaurant market. Each firm has just come up with an idea for a new fast-food menu item which it would sell for $5. Assume that the marginal cost for each new menu item is a constant $3, and the only fixed cost is for advertising. Each company knows that if it spends $16 million on advertising it will get 2 million consumers to try its new product. Burger Prince has done market research which suggests that its product does not have any \"staying\" power in the market. Even though it could get 2 million consumers to buy the product once, it is unlikely that they will continue to buy the product in the future. McDaniel\'s\'s market research suggests that its product is very good, and consumers who try the product will continue to be consumers over the ensuing year. On the basis of its market research, McDaniel\'s estimates that its initial 2 million customers will buy one unit of the product each month in the coming year, for a total of 32 million units. Refer to Scenario 16-4. If Burger Prince decides to advertise its product it can expect toa. incur a loss of $12 million.b. incur a loss of $5 million.c. earn a profit of $5 million. d. earn a profit of $12 million. Solution Option.

Scatter Plot Provide a link for a picture of a scatter plot where the r value is not given. Estimate what you think the r value would be and explain why. Correlation and Causation Read the information in Chapter 3 of your text on correlation and causation and Example 6 titled %u201CSpurious Correlation by Lurking Variables%u201D. This describes an observed correlation that may be caused by the influence of a third variable. Describe and cite a study where the correlation may be spurious. Alternately, you may choose to create and describe your own study where the observed correlation may be influenced by a third variable. Solution Please provide the link for the Text. I couldn\'t find it anywhere... I\'d be happy to help you...

Scale-down models for targets are used for radar cross-section measurements of huge-size objects. Is there any upper limit to the scaling factor on downscale modeling as a 100 m length of target becomes 2 m when downscaled by a factor of 50? Will it satisfy the results? Solution I guess there can be some limitations. If you use a model that is 50 times smaller than the target, the wavelength for the model must be 50 times smaller than the wavelength for the target, so the frequency must be 50 times greater. The imaginary part of the electric permittivity is 4??? (in CGS), where ? is the frequency, ? is the conductivity. So, for example, if your target is made of copper, your model\'s material must have conductivity 50 times greater than that of copper, and there is no such material, as far as I know (I don\'t think using a supercoductive material would help). Similar (but probably less severe) problems can arise with the real part of electric permittivity, as it tends to be smaller for higher frequency..

Scanlin, Inc., is considering a project that will result in initial aftertax cash savings of $1.83 million at the end of the first year, and these savings will grow at a rate of 2 percent per year indefinitely. The firm has a target debtequity ratio of .80, a cost of equity of 12.3 percent, and an aftertax cost of debt of 5.1 percent. The cost-saving proposal is somewhat riskier than the usual project the firm undertakes; management uses the subjective approach and applies an adjustment factor of 1 percent to the cost of capital for such risky projects. What is the maximum initial cost the company would be willing to pay for the project? (Enter your answer in dollars, not millions of dollars, e.g., 1,234,567. Do not round intermediate calculations and round your answer to the nearest whole dollar amount, e.g., 32.)

Say you double your money in three years. Explain why the rate of return in NOT 33.3 percent per year Solution This is because of the simple interest and compound interest. As per simple interest there is no interest on interest. Thus in 3 Years Total interest would be 33.3%*3 = 100%.Thus money would be doubled But when we deposit money then intt paid is compounded.This means we get interest in second year on intt of first year + Principal. Thus interest rate would be less than 33.3% to get the money doubled due to interest on interest in second and third year..

Saunders Corp. has current liabilities of $450,000, a quick ratio of 0.87, inventory turnover of 6.3, and a current ratio of 1.6. What is the cost of goods sold for the company? Solution Quick ratio = (current assets - inventories)/current liabilities 0.87 = (current assets - inventories)/450,000 (current assets - inventories) = 391,500 current ratio = current assets/current liabilities 1.6 = current assets/450,000 or current assets = 720,000 Now, (current assets - inventories) = 391,500 or inventories = 720,000 - 391,500 = 328,500 Inventory turnover = Cost of goods sold/inventory 6.3 = cost of goods sold/328,500 or cost of goods sold = 328,500*6.3 = $2,069,550.

Sarah was contemplating making a contribution to her traditional IRA in 2014. She determined she would contribute $5,000 in December 2014, but forgot about making the contribution until she was preparing her 2014 tax return in February 2015. Use the website of any well-known IRA provider (eg. Fidelity, Vanguard, T. Rowe Price) to determine if Sarah can make a 2014 contribution to her IRA after the tax year has ended. Solution If an individual could not able to make contributions to their IRA account within the end of the tax year both penalty and interest on over dues must be paid. If intentionally mislead the government both criminal and civil penalties must be made on the person. In the present case, S can make a 2014 contribution to her IRA after the tax year has ended but subject to above mentioned restrictions..
