The following changes took place last year in Pavolik Company’s balance sheet accounts:

D = Decrease; I = Increase.

Long-term investments that cost the company $7 were sold during the year for $18 and land that cost $17 was sold for $10. In addition, the company declared and paid $14 in cash dividends during the year. Besides the sale of land, no other sales or retirements of plant and equipment took place during the year. Pavolik did not retire any bonds during the year or issue any new common stock.

The company’s income statement for the year follows:

The company’s beginning cash balance was $100 and its ending balance was $94.

Required:

1. Use the indirect method to determine the net cash provided by operating activities for the year.

2. Prepare a statement of cash flows for the year.

Consider the observations jointly taken on the binary random variables X and Y given in the “Problem 1” worksheet in the Table. 1. Organize the data in a two-way table by counting the number of observations that fall within each of the following cells: {X = 0, Y = 0}, {X = 0, Y = 1}, {X = 1, Y = 0}, and {X = 1, Y = 1}.

2. Use observed cell counts found in part 1 to estimate the joint probabilities for (X = x, Y = y)

3. Find the marginal probabilities of X = x and Y = y

4. Find P(Y = 1|X = 1) and P(Y = 1|X = 0)

5. Find P(X = 1 ∪ Y = 1)

6. Use the estimated marginal probabilities found in part 3 above to compute E(X), E(Y ), V ar(X), and V ar(Y ). Do these agree (at least approximately) with the sample average and sample variance of X and Y?

7. Use the estimated joint probabilities found in part 2 above to compute Cov(X, Y ). 8. Are X and Y independent? Explain.

The following four Cases make different assumptions with respect to the amounts of income and deductions available to Mr. Emerson Comfort for the current taxation year:

Case 1: During the year, Emerson has net employment income of $123,480, interest income of $4,622, and taxable capital gains of $24,246. He has allowable capital losses of $4,835. He has deductible child care costs of $9,372.

Case 2: During the year, Emerson has net business income of $72,438 and a net rental loss of $9,846. His taxable capital gains for the year total $4,233, while his allowable capital losses for the year are $7,489. Because of his very high Earned Income in the previous year, he is able to make $22,000 deductible RRSP contribution.

Case 3: During the year, Emerson has net employment income of $47,234 and a net business loss of $68,672. Capital gains for the year total $12,472 while capital losses are realized in the amount of $9,332. He has deductible child care costs of $3,922.

Case 4: During the year, Emerson has interest income of $6,250, net business income of $43,962, and capital gains of $12,376. He also has a net rental loss of $72,460 and capital losses of $23,874. As he moved to a new work location during the year, he has deductible moving expenses of $7,387.

Required: For each Case, calculate Emerson's Net Income for Tax Purposes. Indicate the amount and type of any loss carry overs that would be available at the end of the current year, or state that no carry overs are available.

Wine Price Study Data

You area an statistician tasked with the challenge of proving that the nation of Remulak is selling its wine in the United States at a price below that which is charged domestically in Remulak. The issue is that the Remulak government is coordinating predatory pricing by subsidizing a lower price charged in the US in order to stimulate export demand for their most prolific product. The data available has been collected from random samples of single bottles of Remulak wine sold in both the United States and in Remulak. Currency exchange experts have adjusted the price charged in Remulak to US Dollars reflecting both the exchange rate differences and differences in real prices between the two nations. You should prepare confidence intervals of the difference of the two pricing levels at both the 95% and 99 % confidence levels. Further, you should conduct an appropriate hypothesis test for a difference in price of $1.70 per bottle lower in the US, which agricultural economists have determined is the minimum difference required to significantly induce increases in US demand for Remulak wine. Please include your math calculations.

The maximum reaction rates (Vmax) for the enzyme invertase were measured from samples at four temperatures. Test the hypothesis that there are no significant differences in the mean invertase reaction rates among temperatures at the 5% level of significance. (8 points)

1. What type of Analysis should you conduct to solve this problem? a. Two-Factor ANOVA b. One-Factor ANOVA c. Paired t-test d. Independent t-test

2. What are the sample sizes for each group? (n1, n2, n3, n4) a. 5, 4, 3, 4 b. 5, 8, 12, 8 c. 4, 5, 3, 4 d. 5, 4, 4, 3

Problem 44 Write a query to display the employee number, last name, first name, and sum of invoice totals for all employees who completed an invoice. Sort the output by employee last name and then by first name (Partial results shown in Figure P7.44).

The amount of skin covering a person's body (in square feet) depends on the person's height and weight. One model for estimating this skin surface area is

A(w, h) = 0.6416w^0.425h^0.725 square feet

for a person weighing w pounds who is h feet tall. If a person 5 feet 11 inches tall who weighs 130 pounds grows 3 inches in height, by approximately how much must this person's weight change if the skin surface area is to remain the same? (Round your answer to two decimal places.)

Write a Matlab function called “SimpleChannel” which takes a signal as an input, simulates a channel and returns the transmitted signal.. SimpleChannel function will add a randomly generated noise (look for “rand” function) to the signal and return it. You can adjust the amplitude of the noise as you want in order to have a distinct noise effect. Then write another matlab code to show the channel noise. First create the signal and then simulate the channel by using your SimpleChannel function. Lastly plot the two signals in the same figure to show the effect of the noise.

Function : [Tran] = SimpleChannel(Rec)

The Signal : x(t) = 2 cos(2πt) + 3 cos(4πt)

Time interval : from 0s to 5s incremented by 0.01s

Note: Don’t forget to put title and label names.

A consulting company was tasked with identifying which market segment would be more profitable, labeled as Segment A or Segment B. A survey was created showing a product to the two different segments, and respondents were asked to rate the product on a scale from 1 to 10 (1 worst, 10 best). Use data from "segment" sheet.

Which of the following are correct? More than one answer is possible.

I am doing a paper in which I have to find the following information:

two web design theories. an example given is Gestalt

two web best practices, an example given is CSS

two technologies, an example given is HTML5

Are there any others? I am kind of lost here. I have no idea what theories, practices or technologies there are out there. Can someone give me a run down of several?
