Motor-Dexterity Test Motor-dexterity tests are often used in psychological studies, especially in neuropsychology. For this task, we are going to test motor-dexterity while looking for signs of frustration. First, take a clean pair of rolled-up socks or some other soft item. Then, have the participants throw it into a hoop you make with your arms. The objective is not to see how well they do the task but to see which hand they use; you are trying to determine dominance. After doing this task, ask the participants which hand they prefer to use when writing. While most will prefer the right, some will prefer the left. If a person says both, ask that individual to write a sentence with both hands, one at a time and the two of you can decide which hand to call dominant. In most cases, people will report they use the right hand more, and they will also unintentionally pick the right hand to throw the object with. If they report left and use the right hand to throw, then record that as mixed, but select the hand they choose as dominant. In the end, you will go with what the participant decides. You are required to record all information on the data sheet. This study involved ten participants. The researcher timed how fast each person put fifteen toothpicks into a mug with each hand. To reduce a significant difference being caused by practice effects, five of the participants started with their dominant hand (DH) and the next set of five started with their nondominant hand (NDH). While they were doing the task, the researcher rated the level of frustration while performing with one hand and then the other one. The researcher was careful not to allow experimenter bias to influence what he or she recorded. Here is the scale used to rate frustration: Very Frustrated Not Very Frustrated 5 4 3 2 1 Look at the data sheet: Participant # Start with NDH (seconds) FL-NDH DH (seconds) FL-DH 1 Right 7 3 6 1 2 Right 10 4 8 2 3 Right 9 3 8 2 4 Left 6 2 7 3 5 Right 8 4 6 1 6 Left 12 5 9 1 7 Left 8 1 7 1 8 Right 11 3 10 2 9 Left 8 2 8 2 10 Left 13 5 9 3 The hypotheses for the study were: People will perform the motor-dexterity task faster with their DH as compared to their NDH. People will show more frustration while using the NDH. Determine the average time with the motor-dexterity test, along with the standard deviation, and then use Minitab to analyze the data with a paired t-test to see if there is a significant performance difference between the two hands. Run another paired t-test to see if there is a difference in frustration (FL) while using the DH versus the NDH. Obtain the results and decide if the hypotheses are supported. Write a summary of the findings. Submit the results and summary of the findings in a 3- to 4-page Microsoft Word document.

A fund manager has a portfolio worth $50 million with a beta of 0.75. The manager is concerned about the performance of the market over the next two months and plans to use three-month futures contracts on a well-diversified index to hedge its risk. The current level of the index is 2,750, one contract is on 250 times the index, the risk-free rate is 6% per annum, and the dividend yield on the index is 2% per annum. a) What position should the fund manager take to eliminate all exposure to the market over the next two months? b) Calculate the effect of your strategy on the fund manager’s returns if the level of the market in two months is 2,700 and 2,800.

Wheat Chex leases a thresher from John Deere. The cost of the thresher is $2,000,000. The lease will last for two years. The company uses straight line depreciation over five years to depreciate the equipment. The estimated salvage value is $1,500,000. The corporate tax ratefc both firms is 40%. The cost of borrowing is 10% and the required rate of return is 15%.
Assume you are John Deere:
Round to the nearest dollar.
What is the after-tax salvage value?
What is the present value of the after-tax salvage value?
If the present value of the other non-SV cashflows is $1,000,000, what is the NAL of the lease?

Pacific Packaging's ROE last year was only 3%; but its management has developed a new operating plan that calls for a debt-to-capital ratio of 60%, which will result in annual interest charges of $128,000. The firm has no plans to use preferred stock and total assets equal total invested capital. Management projects an EBIT of $364,000 on sales of $4,000,000, and it expects to have a total assets turnover ratio of 2.6. Under these conditions, the tax rate will be 40%. If the changes are made, what will be the company's return on equity? Do not round intermediate calculations. Round your answer to two decimal places.
