A U.S. Department of Justice Report included the claim that "in spouse murder cases, wife defendants were less likely yo be convicted than husband defendants". Sample data consisted of 277 convictions among 318 husband defendants, and 155 convictions among 222 wife defendants. Test the stated claim and identify on possible explanation for the results.

Could someone claim their step-son in law as a dependent if they meet the gross income requirements?

The scenerio:

"Ed has supported his stepdaughter, her husband and their child since his wife's death three years ago. Ed promised his late wife that he would support her daughter from a former marriage and her daughter's husband until they both finished college. They live in another state and each make less than $2,000 of gross income per year. Is Ed entitled to dependency exemptions for the three individuals?"

Use supporting IRS codes, regs and court cases to back up answer.

Consider the two-period, Binomial Options Pricing Model. The current stock price S= $105 and the risk-free rate r = 3% per period (simple rate). Each period, the stock price can go either up by 10 percent or down by 10 percent. A European call option (on a non-dividend paying stock) with expiration at the end of two periods (n=2), has a strike price K = $100. The risk-neutral probability of an “up” move is q = (R-D)/(U-D), where R= 1+r.

a). Set out the stock price tree (e.g. in a table), calculate the (no-arbitrage) “fair” price of the call and explain the meaning of “risk neutral valuation” (RNV).

b). Calculate the hedge ratio at t=0 and explain how you can hedge 100 written calls at t=0. Calculate the value of the hedge portfolio at nodes “U” and “D” and hence show that the hedge-portfolio earns the risk-free rate over the first period (i.e. along the path from node t=0, either to node-D or node-U).

c). Calculate the hedge ratio at node-U and explain what this implies for delta hedging (over the next period).

(b) Based on above table, draw a graph with horizontal axis showing the YTM and vertical axis showing prices. Show the graph below. (3 points)

(c) Explain intuitively why we do see a negative relationship between YTM and bond prices. (3 points)

Q1 )
i) A project of room temperature measurement system is given to you; in which you need to design every component of the measurement system. In connection to that, draw the block diagram of the temperature measurement system using passive transducer indicating all the essential elements with input and output of each element. Consider the calibration ratio of (5:1/5) in the display in order to fetch the output.
ii) Analyze the reason, why DC wheat stone bride is not used in thermocouple based measurement system.
iii) A Voltmeter of (0-600V) has a %Limiting error of +1.24% on FSD and % Error of 4%. calculate the following:
a. Limiting error Voltage of the meter.
b. % Limiting error when the meter measures 320V
. c. % Limiting error when the meter measures 120v
. d. The true value, when it measures 320V.
e. Static correction of the meter, for the data mentioned in iv (question above).

Two accountants for the firm of Elwes and Wright are arguing about the merits of presenting an income statement in a multiple-step versus a single-step format. The discussion involves the following 2020 information related to P. Bride Company ($000 omitted). Administrative expense Officers' salaries $4,900 Depreciation of office furniture and equipment 3,960 Cost of goods sold 60,570 Rent revenue 17,230 Selling expense Delivery expense 2,690 Sales commissions 7,980 Depreciation of sales equipment 6,480 Sales revenue 96,500 Income tax 9,070 Interest expense 1,860 Common shares outstanding for 2020 total 40,550 (000 omitted). Prepare an income statement for the year 2020 using the multiple-step form. (Round earnings per share to 2 decimal places, e.g. 1.48.) Prepare an income statement for the year 2020 using the single-step form. (Round earnings per share to 2 decimal places, e.g. 1.48.)

The number of "destination weddings" has skyrocketed in recent years. For example, many couples are opting to have their weddings in the Caribbean. A Caribbean vacation resort recently advertised in Bride Magazine that the cost of a Caribbean wedding was less than $30,000. Listed below is a total cost in $000 for a sample of 8 Caribbean weddings. At the 0.01 significance level, is it reasonable to conclude the mean wedding cost is less than $30,000 as advertised?

1. State the null hypothesis and the alternate hypothesis. Use a 0.01 level of significance. (Enter your answers in thousands of dollars.)

2. State the decision rule for 0.01 significance level. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)

3. Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.)

4. What is the conclusion regarding the null hypothesis?

5. The price of a stock is $40. The price of a one-year European put option on the stock with a strike price of $30 is quoted as $7 and the price of a one-year European call option on the stock with a strike price of $50 is quoted as $5. Suppose that an investor buys 100 shares, shorts 100 call options, and buys 100 put options. a. Construct a payoff and profit/loss table b. Draw a diagram illustrating how the investor’s payoff and profit or loss at expiation.
