Suppose that you as a researcher wanted to examine the impact of police officer rank on perceptions of friendliness by citizens in College Park, MD. Rank is measured as patrol officer, sergeant or captain, and citizen perception is captured by a scale ranging from -50 to 50 and measured in a survey given to 1,000 randomly selected people after an interaction with a police officer. 500 people talked to a patrol officer, 300 talked to a sergeant and 200 people talked to a captain.

3. What is the a) unit of observation and b) reasonable population for this sample?

4. Identify the a) independent and b) dependent variables.

5. For each variable, name what kind of variable it is (nominal, ordinal, interval, or ratio).

1. On January 1, 2017, Park Rapids Lumber Company issued $80 million in 20-year, 10.5% bonds payable. Interest is payable semiannually on June 30 and December 31.

1. Record the journal entry when the bonds were issued on January 1, 2017 when the market rate was 10%, and record the payment of bond interest on June 30^th and December 31^st for 2017 and 2018.

      b.    Compute the net bond liability at December 31, 2018.

            c. On January 1, 2019 the bonds were repurchased for 101. Record the journal entry for the repurchase of the bonds.   This transaction is very similar to the sale of a fixed asset. 101 is the same as 101% of the face value of the bond.

A-One Landscapers, Inc., owes Friendly Finance Company $5,000. A-One enters into a contract with Suburban Office Park under which A-One promises to maintain the landscaping on Suburban’s property and Suburban promises to pay Friendly Finance the amount that will be due A-One until A-One’s debt to Friendly Finance is paid. A-One performs as promised, but Suburban does not pay Friendly Finance.

1.   What is the basis for a claim by Friendly Finance against Suburban?
2.   Will Friendly Finance be successful if it sues Suburban based on your answer to 1., above?
3.   Explain why or why not Friendly Finance will succeed in such a suit. In your answer state the general legal principle and then apply it to these facts.

Consider the following independent situations, all of which apply to audits of entities for the year ended 31 December 2019:

(i) In July 2019, Alpha Ltd started using a new general ledger software package. The Financial Controller is impressed with the new system, because management accounts are easily produced and allow detailed comparisons with budgets and prior-period figures across product lines and geographical areas. The conversion to the new system went smoothly. As it is a popular computer package, it required only minor modifications.

(ii) As part of a computer systems conversion in Beta Ltd, the position of Systems Administrator was created. This position is responsible for all systems maintenance, including data backups and modifications. These tasks were previously the responsibility of the Accountant.

(iii) Gamma Ltd is a large supermarket chain with outlets in all major cities in the country. In August 2019 Gamma Ltd contracted out its payroll data processing in each city to an independent computer service provider.

(iv) Delta Ltd is a long established firm which has been operating a hotel for over 10 years. During this time, it has adopted a conservative business strategy that has seen it produce adequate, though slightly unimpressive, results. A new CEO was appointed to run the firm from September 2019. He has already released his plans for renovating the hotel, despite not officially serving as CEO yet. You have also heard him discuss the implementation of a new marketing strategy to improve occupancy rates.

Required:

For each situation (i) to (iv) above.

(a) State whether Inherent Risk, Control Risk or Detection Risk have increased or decreased.

(b) Provide an explanation for your answer in (a)

1. A study was conducted to examine whether the perception of service quality at hotels differed by gender. Hotel guests were randomly selected to rate hotel service, and each rating was then transferred into a standardized score. By comparing the scores observed from the sample of male guests and the sample of female guests, researchers then wished to determine if there is evidence of a difference in average rating when awarded by males, μ ₁, and the average rating when awarded by females, μ ₂. A summary of the sampled guest scores are provided in the table below :

2. 
   i) Carry out a hypothesis test for a significant difference between the two population means, at significance level α = 0.05.
   The hypotheses being tested are:
   H ₀: μ ₁ - μ ₂ = 0
   H _a: μ ₁ - μ ₂ ≠ 0.
   Complete the test by filling in the blanks in the following:
   • An estimate of the difference in population means is .
   • Assuming the population standard deviations are equal, σ₁=σ₂, the pooled estimate, s_p, is  and the standard error is .
   • The distribution is  (examples: normal / t12 / chisquare4 / F5,6).

The test statistic has value TS=  .
Testing at significance level α = 0.05, the rejection region is:
less than  and greater than  (3 dec places).
There  (is evidence/is no evidence) to reject the null hypothesis, H ₀ of no difference between the two population means, μ ₁ and μ ₂.

ii) Estimate the difference in population means by calculating a 95% confidence interval.
The difference between the population means, the mean of population 1, μ ₁, minus the mean of population 2, μ ₂, is estimated to be between________  and__________ .
