The manager of a resort hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim.

(a)

Which form of the hypotheses should be used to test the manager's claim? Explain.

H₀: μ ≥ 600

H_a: μ < 600

H₀: μ ≤ 600

H_a: μ > 600

H₀: μ = 600

H_a: μ ≠ 600

A) The hypotheses H₀: μ ≥ 600 and H_a: μ < 600 should be used because the accountant wants to test the manager's claim that the mean guest bill μ is greater than or equal to 600 and find evidence to support μ < 600.

B)The hypotheses H₀: μ ≤ 600 and H_a: μ > 600 should be used because the accountant wants to test the manager's claim that the mean guest bill μ is less than or equal to 600 and find evidence to support μ > 600.   

C)The hypotheses H₀: μ = 600 and H_a: μ ≠ 600 should be used because the accountant wants to test the manager's claim that the mean guest bill μ is equal to 600 and find evidence to support μ ≠ 600.

(b)

What conclusion is appropriate when

H₀

cannot be rejected?

A)We are able to conclude that the manager's claim is wrong. We can conclude that μ = 600.

B)We are not able to conclude that the manager's claim is wrong.We cannot conclude that μ > 600.    

C) We are not able to conclude that the manager's claim is wrong. We cannot conclude that μ ≠ 600.

D) We are able to conclude that the manager's claim is wrong. We can conclude that μ ≤ 600.

E) We are not able to conclude that the manager's claim is wrong. We can conclude that μ ≥ 600.

(c)

What conclusion is appropriate when

H₀

can be rejected?

A) We are not able to conclude that the manager's claim is wrong. We can conclude that μ < 600.

B) We are not able to conclude that the manager's claim is wrong. We can conclude that μ > 600.    

C) We are able to conclude that the manager's claim is wrong. We can conclude that μ < 600.

D)We are able to conclude that the manager's claim is wrong. We can conclude that μ ≠ 600.

E) We are able to conclude that the manager's claim is wrong. We can conclude that μ > 600.

Following are the number of victories for the Blue Sox and the hotel occupancy rate for the past eight years. You have been asked to test three forecasting methods to see which method provides a better forecast for the Number of Blue Sox Wins.

For the following, you are to provide all forecasts to one decimal place (example, 93.2)

You are asked to forecast the Number of Blue Sox Wins for Year 9. Although you believe there might be a linear regression relationship, your boss has told you to only consider the following three forecasting methods:

• 3-period moving average
• 3-period weighted moving average given the weights of 0.7 for the most recent period and 0.2 for the next most recent period, and the remaining weight (s) consistent with this method as we have used in class, and
• exponential smoothing with α = 0.25 and the best forecast available for the Number of Blue Sox Wins is for Year 2 which is 66.0.

a) What is the forecast from each of these methods for Year 9?

b) Which forecasting method provides the better forecast for Year 9? Why? Your selection criteria must be based on one of the numerical evaluation methods we have used on the homework this term using the forecast results for Year 5 through Year 8.

A public health researcher wonders if the well-being of a nation’s health care system influences its infant mortality rate. To investigate this, she collected data on well-being of the health care system (the nation’s number of people per hospital bed; a lower number indicates a stronger health care system) and infant mortality rate (number of infant deaths per 1,000 births) from 6 countries.

a) Calculate the correlation between infant mortality rate and people per hospital bed in this sample of countries. Show all of your calculation work.

b) Interpret the result you obtained in a).

c) Calculate the regression for the relationship between infant mortality rate and people per hospital bed. Show all of your calculation work.

d) Interpret the results you obtained in c).

e) If a country has 150 people per hospital bed, what do the results of the analysis here predict for that country’s infant mortality rate? Show all of your work.

f) What other country-level variables may influence a country’s infant mortality rate? Give at least one and explain why you think this variable influences the infant mortality rate

Barry Potter and Winnie Weasley are considering making an S election on March 1, 2019, for their C corporation, Omniocular. However, first they want to consider the implications of the following information:

• Winnie is a U.S. citizen and resident.
• Barry is a citizen of the United Kingdom, but a resident of the United States.
• Barry and Winnie each own 50 percent of the voting power in Omniocular. However, Barry's stock provides him with a claim on 60 percent of the Omniocular assets in liquidation.
• Omniocular was formed under Arizona state law, but it plans on eventually conducting some business in Mexico.

For the remainder of the problem, assume Omniocular made a valid S election effective January 1, 2019. Barry and Winnie each own 50 percent of the voting power and have equal claim on Omniocular's assets in liquidation. In addition, consider the following information:

• Omniocular reports on a calendar tax year.
• Omniocular's earnings and profits as of December 31, 2018, were $55,000.
• Omniocular's 2018 taxable income was $15,000.
• Omniocular's assets at the end of 2018 are as follows:

*$110,000 under FIFO accounting.

• On March 31, 2019, Omniocular sold the land for $42,000.
• In 2019, Omniocular sold all the inventory it had on hand at the beginning of the year. This was the only inventory it sold during the year.

• Assume that if Omniocular were a C corporation for 2019, its taxable income would have been $88,500.

E. Assume Barry's basis in his Omniocular stock was $40,000 on January 1, 2019. What is his stock basis on December 31, 2019?

PERFORMANCE EVALUATION

Julie Miller supervisor of housecleaning for Hotel Minto, was surprised by her summary report for March given below.

Julie was disappointed. She thought she had done a good job controlling housekeeping labor and towel usage, but her performance report revealed an unfavorable variance of $12,111. She had been hoping for a bonus for her good work, but now expected a series of questions from her manager.

The cost budget for housekeeping is based on standard costs. At the beginning of a month, Julie receives a report from Hotel Minto’s Sales Department outlining the planned room activity for the month. Julie then schedules labor and purchases using this information. The budget for the housekeeping was based on 8,000 room nights. Each room night is budgeted based on the following standards for various materials, labor, and overhead:

With 8,900 room nights sold, actual costs and usage for housekeeping during April were:

Required:

You have been asked to re-evaluate Julie’s performance.

Prepare a report to Julie’s boss demonstrating and explaining your findings; including your suggestions for performance evaluation methods and measures in the future.

Explain what your report suggests about Kathys departiment erformance.
