Less: Accumulated depreciation—equipment 5,000,000 35,000,000
Total plant assets $52,400,000
During 2011, the following selected cash transactions occurred.
Apr. 1 Purchased land for $2,200,000.
May 1 Sold equipment that cost $600,000 when purchased on January 1, 2004.
The equipment was sold for $170,000.
June 1 Sold land for $1,800,000. The land cost $1,000,000.
July 1 Purchased equipment for $1,300,000.
Dec. 31 Retired equipment that cost $500,000 when purchased on December
31, 2001. No salvage value was received.
Instructions
(a) Journalize the transactions. (Hint: You may wish to set up T accounts, post beginning
balances, and then post 2011 transactions.) Rijo uses straight-line depreciation for
buildings and equipment. The buildings are estimated to have a 40-year useful life and
no salvage value; the equipment is estimated to have a 10-year useful life and no sal-
vage value. Update depreciation on assets disposed of at the time of sale or retirement.
(b) Record adjusting entries for depreciation for 2011.
(c) Prepare the plant assets section of Rijo’s balance sheet at December 31, 2011.

A machine shop owner wants to decide whether to purchase a new drill press, new lathe, or new grinder. As shown in the following table, the profit from each purchase will vary depending on whether or not the owner wins a government contract, with the owner estimating a probability of .60 of winning the contract:

Before deciding which item to purchase, the owner needs to decide whether or not to hire a military consultant to assess whether the shop will get the government contract. The track record of the military consultant in predicting whether companies would win government contracts is as follows: For 90% of the companies that won contracts, the consultant had predicted they would win, and for 70% of the companies that lost contracts, the consultant had predicted they would lose. [adapted from Taylor (2004)]

(a) Assuming the consultant would not charge for his assessment, determine the optimal strategy based on the expected value criterion, and state its expected value. (Draw then solve the Decision Tree below)

(b) Determine EVSI (with the consultant regarded as the sample information).

(c) If the consultant were to charge $5,000 for his assessment, what would be the optimal strategy and its expected value?

The National Sleep Foundation used a survey to determine whether hours of sleeping per night are independent of age (Newsweek, January 19, 2004). The following show the hours of sleep on weeknights for a sample of individuals age 49 and younger and for a sample of individuals age 50 and older.

1. Conduct a test of independence to determine whether the hours of sleep on weeknights are independent of age. Use  = .05. Use Table 12.4.
   
   Compute the value of the  ² test statistic (to 2 decimals).
   
   
   The p value is Selectless than .005between .005 and .01between .01 and .025between .025 and .05between .05 and .10greater than .10Item 2
   
   What is your conclusion?
   SelectConclude age and hours of sleep are not independentCannot reject the assumption that age and hours of sleep are independentItem 3
   
2. Using the total sample of 500, estimate the percentage of people who sleep less than 6, 6 to 6.9, 7 to 7.9, and 8 or more hours on weeknights (to 1 decimal).

   6 to 6.9 hours	%
   7 to 7.9 hours	%

The following data were recorded as part of a study on sustainable farming techniques that took place in Boone County, IA. (Davis, Adam S. et al. Increasing Cropping System Diversity Balances Productivity, Profitability and Environmental Health. PLOS ONE. October 10, 2012. DOI:10.1371/journal.pone.0047149) Means are for the April-November growing seasons.

(1): Construct a two-way scatter plot for “air temperature” against the “total precipitation” and on a separate graph construct a two-way scatter plot for “air temperature” against “log of total precipitation”. Looking at the two graphs you plotted, explain as to which of these two do you consider to be closest to a linear relationship?

(2): At the 0.05 level of significance, test the null hypothesis that the (“air temperature” and the “total precipitation”) population correlation coefficient [ρ] is equal to 0.

(3): Compute the equation of the linear regression relationship between the “air temperature” and “total precipitation”.

Sachs Brands' defined benefit pension plan specifies annual retirement benefits equal to: 1.5% × service years × final year's salary, payable at the end of each year. Angela Davenport was hired by Sachs at the beginning of 2004 and is expected to retire at the end of 2038 after 35 years' service. Her retirement is expected to span 18 years. Davenport's salary is $98,000 at the end of 2018 and the company's actuary projects her salary to be $320,000 at retirement. The actuary's discount rate is 8%.

1. What is the company's projected benefit obligation at the beginning of 2018 (after 14 years' service) with respect to Davenport?(Round your final answer to nearest whole dollar)

2.Estimate by the projected benefits approach the portion of Davenport's annual retirement payments attributable to 2018 service.

3.What is the company's service cost for 2018 with respect to Davenport?(Round your final answer to nearest whole dollar)

4.What is the company's interest cost for 2018 with respect to Davenport?(Round your final answer to nearest whole dollar)

5.Combine your answers to requirements 1, 3, and 4 to determine the company's projected benefit obligation at the end of 2018 (after 15 years' service) with respect to Davenport. (Round your final answer to nearest whole dollar)
