A transformer is plugged into a regular U.S. Wall outlet. There are 200 turns in the primary coil, and 4000 turns in the secondary coil. A) What is the rms voltage and peak voltage on the secondary coil? (two answers) B) An electrical worker accidently grabs one of the loops of the secondary coil with a single bare hand. Her other hand is in midair, and both of his shoes are firmly on the ground. The resistance in her body is negligible compared to his shoes. Each shoe has a 2mm-thick rubber sole, with a sole-area of 0.02 m2 . The rubber has a resistivity of 1 MW•m. What is the rms current that runs through the worker's torso? (Warning: there are two shoes.) Hint: A drawing is almost certainly helpful. C) There is a 50-Amp fuse on the wall outlet. Will this fuse trip before the full current (calculated in part B) passes through the worker's body? (Careful: There is a complication here, since the fuse is on the primary-coil side of the transformer.).

Toyo Japan plant manufactures three product lines, all multi-purpose kitchenware. The plant’s three product models are the Product 1 (P1), the Product 2(P2), and the Product 3 (P3). Until recently, the plant used a job-order product-costing system, with manufacturing overhead applied on the basis of direct-labor hours. The following table displays the basic data upon which the traditional costing system was based.

The annual budgeted overhead is $1,224,000, and the company’s predetermined overhead rate is
$12 per direct-labor hour. The product costs for the three product models, as reported under the plant’s traditional costing system, are shown in the following table.

Toyo Japan’s pricing policy is to set a target price for each product equal to 130 percent of the full product cost. Due to price competition from other appliance manufacturers, P1 units were selling at $525, and P2 units were selling for $628. These prices were somewhat below the firm’s target prices. However, these results were partially offset by greater-than-expected profits on the P3 product line. Management had raised the price on the P3 model to $800, which was higher than the original target price. Even at this price, Kitchen King’s customers did not seem to hesitate to place orders, Moreover, the company’s competitiors did not mount a challenge in the market for the P3 product line. Neverthless, concern continued to mount in Toledo about the difficulty in the P1 and P2 markets. After all, these were the plant’s breadand-butter products, with projected annual sales of 5,000 P1 units and 4,000 P2 units.
Toyo Japan’s director of cost management, Angela Ramirez, had been thinking for some time about a refinement in the Toledo plant’s product-costing system. Ramirez wondered if the traditional, volume-based system was providing management with accurate data about product costs. She had read about activity-based costing, and wondered if ABC would be an improvement to the plant’s productcosting system. After some discussion, an ABC proposal was made to the company’s top management, and approval was obtained. The data collected for the new ABC system is displayed in the following table.

Complete an activity-based costing analysis for Toyo Japan’s three product lines regarding machine related, and material handling activities.

1. The table below contains the widths of a product, showing 10 samples of size 5 measurements each.

1. Construct a sample means, X control chart and R chart for the above data.
2. Identify those subgroup means which are outside the control limits.
3. Comment on the process.

The data shown below contains the monthly sales (in thousands of dollars) at a local department store for each of the past 24 months. Copy the data to Excel, perform a runs test, and compute a few autocorrelations to determine whether this time series is random. Give your conclusion by referring to the results of your runs test and autocorrelations (no need to try to attach the Excel output in this text box, just mention the specific values you refer to).

Wilson Publishing Company produces books for the retail market. Demand for a current book is expected to occur at a constant annual rate of 7200 copies. The cost of one copy of the book is $13.5. The holding cost is based on an 21% annual rate, and production setup costs are $170 per setup. The equipment on which the book is produced has an annual production volume of 25000 copies. Wilson has 250 working days per year, and the lead time for a production run is 12 days. Use the production lot size model to compute the following values:

Minimum cost production lot size. Do not round intermediate values and round your final answer to two decimal places.

Q* = Number of production runs per year. Do not round intermediate values and round your final answer to two decimal places.

3. Profit maximization using total cost and total revenue curves

Suppose Ana runs a small business that manufactures shirts. Assume that the market for shirts is a competitive market, and the market price is $20 per shirt.

The following graph shows Ana's total cost curve.

Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for shirts quantities zero through seven (inclusive) that Ana produces.

Calculate Ana's marginal revenue and marginal cost for the first seven shirts she produces, and plot them on the following graph. Use the blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost at each quantity.

Ana's profit is maximized when she producesshirts. When she does this, the marginal cost of the last shirt she produces is, which is (less or greater) than the price Ana receives for each shirt she sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize her profit) is, which is (Greater or less) than the price Ana receives for each shirt she sells. Therefore, Ana's profit-maximizing quantity corresponds to the intersection of the   curves. Because Ana is a price taker, this last condition can also be written as   .

When only two treatments are involved, ANOVA and the Student’s t test (Chapter 11) result in the same conclusions. Also, for computed test statistics, t^₂ = F. To demonstrate this relationship, use the following example. Fourteen randomly selected students enrolled in a history course were divided into two groups, one consisting of 6 students who took the course in the normal lecture format. The other group of 8 students took the course as a distance course format. At the end of the course, each group was examined with a 50-item test. The following is a list of the number correct for each of the two groups.

1= Complete the ANOVA table. (Round your SS, MS, and F values to 2 decimal places and p value to 4 decimal places.)?

2=a-2. Use a α = 0.01 level of significance. (Round your answer to 2 decimal places.)

2. Using the t test from Chapter 11, compute t. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)

3. There is any difference in the mean test scores.
