Investment in Trading and AFS Securities

In 2019, a company purchases debt securities at a par value of $500,000. Their year-end value is $520,000. In 2020, these securities are sold for $525,000 and new securities are purchased for $700,000. At the end of 2020, the securities have not yet been sold, and have a value of $600,000.

Required
Prepare the journal entries to record the above information for 2019 and 2020, assuming that:

a. The securities are categorized as trading securities.

A medical researcher believes that a drug changes the body's temperature. Seven test subjects are randomly selected and the body temperature of each is measured. The subjects are then given the drug, and after 30 minutes, the body temperature of each is measured again. The results are listed in the table below. Is there enough evidence to conclude that the drug changes the body's temperature?

Let d=(body temperature after taking drug)−(body temperature before taking drug)d=(body temperature after taking drug)−(body temperature before taking drug). Use a significance level of α=0.02 for the test. Assume that the body temperatures are normally distributed for the population of people both before and after taking the drug.

Step 1 of 5: State the null and alternative hypotheses for the test.

Step 2 of 5: Find the value of the standard deviation of the paired differences. Round your answer to two decimal places.

Step 3 of 5: Compute the value of the test statistic. Round your answer to three decimal places.

Step 4 of 5: Find the p-value for the hypothesis test. Round your answer to four decimal places.

Step 5 of 5: Draw a conclusion for the hypothesis test.

1.Question1
Suppose there is an island which used to have no trac connection with the outside world.
After several years, airports are built up in the island and there are planes to do the
transportation, so it is possible for the island to have international trade now.
(1) Before the international trade, the price of vehicles in the local market of the island is
higher than the world price, should the island imports or exports vehicles in the international
trade?
(2) Draw the graph of the supply and demand curve of the island's vehicles market.
Mark the size change of the consumer surplus and producer surplus before and after the
international trade. After the international trade, how does the consumer surplus change?
How does the producer surplus change? How does the total surplus change?
(3) Suppose the local government decide to impose a tari on the vehicles imported
from the outside world, but the price of the vehicles from the outside world plus the tari
are lower than the local market price of vehicle before the free international trade. Draw the
graph of the supply and demand curve of the island's vehicles market with tari. Mark the
size change of the consumer surplus and producer surplus before and after the international
trade. After the international trade, how does the consumer surplus change? How does the
government revenue change? How does the producer surplus change? How does the total
surplus change? You can draw the graph based on (2).

Consider the following variation of Table 11-1 for the U.S. semiconductor market

1. Fill in the values for W, X, Y, and Z.
2. Suppose that before NAFTA, the United States had a 16% tariff on imported semiconductors. Which country supplied the U.S. market? Is it the lowest-cost producer?
3. After NAFTA, who supplies the U.S. market? Has either trade creation or diversion occurred because of NAFTA? Explain.
4. Now suppose that before NAFTA, the United States had an 8% tariff on imported semiconductors. Then repeat parts (b) and (c).
5. In addition to the assumptions made in (d), consider the effect of an increase in high-technology investment in Canada due to NAFTA, allowing Canadian firms to develop better technology. As a result, three years after the initiation of NAFTA, Canadian firms can begin to sell their products to the United States for $40. What happens to the U.S. trade pattern three years after NAFTA? Has either trade creation or diversion occurred because of NAFTA? Explain.

Part II: gdb (Debugging under Unix)

1. create a new directory named by Inlab6Part2
2. enter the directory Inlab6Part2
3. create a file named by reverse_new.c with the following contents:

/*reverse.c */

#include <stdio.h>

void reverse(char *before, char *after);

main()

{

      char str[100];    /*Buffer to hold reversed string */

      reverse("cat", str); /*Reverse the string "cat" */

      printf("reverse(\"cat\")=%s\n", str); /*Display result */

      reverse("noon", str); /*Reverse the string "noon" */

      printf("reverse(\"noon\")=%s\n", str); /*Display result */

}

void reverse(char *before, char *after)

{

      int i;

      int j;

      int len;

      len=strlen(before);

      for(j=len, i=0; j>=0; j--, i++)

                  after[i]=before[j];

      after[len]=NULL;

}

4. See the output, is it right?
5. compile reverse_new.c and prepare the debugger information at the same time.(To debug a program, it must have been compiled using the –g option to gcc, which places debugging information into the object module.)
6. Now you start the debugger and fix the errors.
   1. set breakpoint in line 1 and then go through step by step, print the value of arguments after each step.
   2. make sure you use most of the commands in the handout, and then print everything you did(all the commands and outputs).

The 10% bonds payable of Hanna Co. had a carrying amount of $4,160,000 on December 31, 2019. The bonds, which had a face value of $4,000,000, were issued at a premium to yield 8%. Hanna uses the effective-interest method of amortization. Interest is paid on June 30 and December 31. On June 30, 2020, several years before their maturity, Hanna retired the bonds at 105 plus accrued interest. The loss on retirement, ignoring taxes, is

Problem 1) Today, April 1^st 2020, I put $1000 into the bank. Every month thereafter I added the same amount, plus $20 more than the month before (i.e. $1020, $1040, $1060, etc.) If the sign on the door of my bank says they pay 6% nominal yearly interest, how much will I be able to take out of the bank on January 1^st, 2023. Draw a cash-flow diagram.

Tokyo 2020 Olympics officially postponed until 2021

1. Do you think the Olympics made the right choice in postponing the games?
2. If you were an athlete who was performing, how would you feel?
3. Do you believe there will be a chance that the Olympics could be held earlier than the postponed date?
4. How does the postponement affect ticket holders? Should tickets be considered valid?
5. Do you think this pandemic will be contained before the games?

During the current year, Ron and Anne sold the following assets: (Use the dividends and capital gains tax rates and tax rate schedules.)

*$30,000 of the gain is 25 percent gain (from accumulated depreciation on the property).

Ignore the Net Investment Income Tax.

a. Given that Ron and Anne have taxable income of only $22,200 (all ordinary) before considering the tax effect of their asset sales, what is their gross tax liability for 2020 assuming they file a joint return? (Round all your intermediate computations to the nearest whole dollar amount.)

b. Given that Ron and Anne have taxable income of $402,200 (all ordinary) before considering the tax effect of their asset sales, what is their gross tax liability for 2020 assuming they file a joint return? (Round all your intermediate computations to the nearest whole dollar amount.)
