Study a consumer product that your group might consider buying. Select a flatscreen TV, home theater system, computer, digital camera, espresso machine, car, SUV, hot tub, or some other product. Next, research the product as described in Chapter 10. Use at least five primary and five secondary sources in researching your topic. Your primary research will be in the form of interviews with individuals (owners, users, salespeople, technicians) in a position to comment on attributes of your product. Your secondary research will be in the form of print or electronic sources, such as magazine articles, owner manuals, and Web sites. Be sure to use electronic databases and the Web to find appropriate articles.

Your report should analyze and discuss at least three comparable models or versions of the target product. Decide what criteria you will use to compare the models, such as price, features, warranty, service, and so forth. The report should include these components: letter of transmittal, table of contents, executive summary, introduction (including background, purpose, scope of the study, and research methods), findings (organized by comparison criteria), summary of findings, conclusions, recommendations, and bibliography.

Suppose a country’s production function has three factors of production: K—capital, L—the number of workers, and H—human capital. The production function is Y = (K^0.3)(L^0.4)(H^0.3). (a) What is the marginal product of labor? How does human capital affect the MPL?

(b) What is the marginal product of human capital? How does human capital affect the MPH?

c) What share of total income is paid to labor? What share of total income is paid to human capital?

(d) What share of total income would workers appear to receive?

(e) An unskilled worker earns the MPL, whereas a skilled worker earns the MPL plus the MPH. Using your above answers, find the ratio of the skilled wage to the unskilled wage. How does human capital affect this ratio? Explain.

1. For a scanner with a maximum gradient strength of 20 mT m^-1 and a minimum transmitted bandwidth of 0.9 kHz, what is the thinnest slice that can be selected? (? = 42.6 MHz T^-1).

2. Which of the following is the bandwidth of a pulse with frequencies from 60.0015 to 60.0045 MHz?

(a) 3 kHz (b) 3 MHz (c) 0.3 Mhz (d) 60.0030 MHz.

3. Convert the following gradient strengths, expressed in terms of frequency, into T/m. (Assume ? = 42.6 MHz/T).

(a) 2 MHz/m; (b) 1 MHz/m; (c) 0.3 MHz/m.

4. Calculate the slice thickness for each of the gradients in problem 3 if the pulse bandwidth is 1.5 kHz.

5. Using the field gradient shown, which type of slice will be selected? Transaxial, Sagattal, or Coronal?

Corporation makes a product with the following standard costs:

The company reported the following results concerning this product in August.

The company applies variable overhead on the basis of direct labor-hours. The direct materials purchases variance is computed when the materials are purchased.

The variable overhead rate variance for August is:

An certain brand of upright freezer is available in three different rated capacities: 16 ft³, 18 ft³, and 20 ft³. Let X = the rated capacity of a freezer of this brand sold at a certain store. Suppose that X has the following pmf.

(a) Compute E(X), E(X²), and V(X).

(b) If the price of a freezer having capacity X is 60X − 650, what is the expected price paid by the next customer to buy a freezer?

(c) What is the variance of the price paid by the next customer?

(d) Suppose that although the rated capacity of a freezer is X, the actual capacity is h(X) = X − 0.009X². What is the expected actual capacity of the freezer purchased by the next customer?
