The following table identifies a group of children by one of four hair colors, and by type of hair.

• Part (a)

  Complete the table.

  Hair Type	Brown	Blond	Black	Red	Totals
  Wavy	19		13	5	42
  Straight	78	14		14
  Totals		19			211

• Part (b)

  What is the probability that a randomly selected child will have wavy hair? (Enter your answer as a fraction.)

• Part (c)

  What is the probability that a randomly selected child will have either brown or blond hair? (Enter your answer as a fraction.)

• Part (d)

  What is the probability that a randomly selected child will have wavy brown hair? (Enter your answer as a fraction.)

• Part (e)

  What is the probability that a randomly selected child will have red hair, given that he has straight hair? (Enter your answer as a fraction.)

• Part (f)

  If B is the event of a child having brown hair, find the probability of the complement of B. (Enter your answer as a fraction.)

• Part (g)

  If B is the event of a child having brown hair, what does the complement of B represent?

  The complement of B would be the event of a child having blond or black hair.The complement of B would be the event of a child having blond hair.    The complement of B would be the event of a child not having brown hair.The complement of B would be the event of a child having wavy or straight hair.

Suppose you have been hired by a pharmaceutical firm to perform a "clinical trial" to test for possible behavioral effects of a new pain reliever.  One of the things you decide to test for is the existence of depression‑producing side effects.  You use a standard instrument (test) for measuring depression.  The overall long‑term average for a normal adult population is 50 with a standard deviation of 10.  Higher numbers mean a greater amount of depression.  You have the resources of testing 18 people on this depression test after they have taken the new pain reliever.  Make up 16 data points such that the mean is between 52 and 56and the standarddeviation is at not too far from 10--say between 7 and 15).  Scores:

_____25_____    ___65_______    _____45_____    _____35_____    ____55______    _____65_____

___65_______    _____30_____    ___65_______    _____55_____    ___49_______    ____59______

_____59_____    ____69______    _____59_____    ____48______    

1.         Confirm that the mean is between 52 and 56.  If it is not, then change your data and start over.

2.         Find s (unbiased) of above data, confirming that s is between 7 and 15. If it is not, then change your data and start over.  Explain how it was obtained or attach work.

3.    State Ho using symbols and also in words.

4.    State H₁ using symbols and also in words.

5.         In everyday language say what a Type 1 error would be for this experiment?  

6.         In everyday language say what a Type 2 error would be for this experiment?  

7.         Which one would be worse?  Why?

8.         Based on your answer to #5-7, choose an appropriate alpha level and discuss the choice.

1. alpha = _______  Reasons:

2. What are the consequences of a higher level?  

3. What are the consequences of a lower level?  

9.          a.        Compute the obtained z value.  (Show work).  

           b.            What is the probability of getting a z value as unusual as the one you got simply due to random chance (i.e. add up areas in both tails)?

c.         Compare your answer in 9b to alpha and state your conclusion.

10.       Pretend that you do not know the population standard deviation

1. Write down s (unbiased) from #2.

2. Find .  (Show work).

3. Compute the obtained t‑value  (Show work).

4. Enter the df.  ______________

5. Find the critical t‑value for your chosen alpha level (two-tailed test).

6. Compare the critical t‑value to the obtained t‑value and state your conclusion.

11.         a.       Compute the confidence interval of the population mean based solely on your 18 data points.  Use the same alpha level as above.  (E.g. if your alpha level is 0.1, then this is your 90% confidence interval)

b.         Is the population mean included in your confidence interval?  Is this consistent with your conclusion in 10f?   Explain.

12.       Given your decision in 10f, what are the two possible outcomes of this experiment? (HINT: Consider the 2 x 2 hypothesis outcome table discussed in class)

13.       What are some methodological flaws in this experimental design and how could they be corrected?

Please respond to the following:

-Use the Internet to research a publicly traded company that received an unqualified audit report from external auditors and faced accusations of reporting false or misleading accounting information.

-Discuss the departures from generally accepted accounting principles (GAAP) that you have researched, and give your opinion as to whether or not the Public Company Accounting Oversight Board (PCAOB) should levy sanctions against the CPA firm for issuing the unqualified report.

-Identify the sanctions and section of the report the company should have modified to address departures from GAAP. Support your position.

-Compare the code of professional conduct for CPAs to the code of professional conduct for accountants who are non-CPAs.

-Determine the major ethical issues created by the mergers of public accounting firms with non-CPA firms that perform accounting services. Explain your rationale.

The Conceptual Framework for the Preparation of Financial Statements describes the basic concepts that underlie the preparation of financial statements for presentation to external users who include shareholders. The contents of The Conceptual Framework serve as a guide to development of International Financial Reporting Standards (IFRSs). It seeks to share understanding of certain key terms that are used in IFRSs and may be referred to by directors when handling a business matter that is not directly addressed by any issued standard.

Required:

1. Describe four primary users of financial statements and explain how they benefit from the application of the Conceptual Framework and IFRSs to preparation of financial statements.                                                                                                ( 4 marks)
2. Explain what measurement in financial statements is and give examples (use information in the solution to Question 1 of Section A) of initial measurement and subsequent measurement.                                                                            ( 4 marks)
3. Explain what recognition in financial statements is and describe the general criteria for recognising an income and an expense in financial statements.  
4. Explain the significance of fundamental characteristics of financial information and discuss how enhancing characteristics supplement primary ones.                                                                                                               (Total: 20 marks)

sometimes in order to simulate more cunsumer and business spending, the federal government will compel banks to relax lending standards for a time to entice individuals and business organizations to take out more loans than they would do under more restrictive standards

is the relaxing of lending standards a wise government policy to implement from time to time, or is the risk to the overall economy too great to make use of such a policy?

explain in detail why or why not
