Money reports that the average annual cost of the first year of owning and caring for a large dog in 2017 is $1,448. The Irish Red and White Setter Association of America has requested a study to estimate the annual first-year cost for owners of this breed. A sample of 50 will be used. Based on past studies, the population standard deviation is assumed known with

σ = $265.

A. What is the margin of error for a 95% confidence interval of the mean cost in dollars of the first year of owning and caring for this breed? (Round your answer to nearest cent.)

B. The DATAfile Setters contains data collected from fifty owners of Irish Setters on the cost of the first year of owning and caring for their dogs. Use this data set to compute the sample mean. Using this sample, what is the 95% confidence interval for the mean cost in dollars of the first year of owning and caring for an Irish Red and White Setter? (Round your answers to nearest cent.)

A term spread is the difference between the rate on the 10 year treasury bond and a 30 year corporate bond

TRUE OR FALSE

1. A company uses the periodic average cost method to account for inventory. For the year, the company had the following beginning inventory and purchases:
   

Sales for the year totaled 1,000 units, leaving 300 units on hand at the end of the year. The company reported ending inventory for $900,000. Which of the following is correct?

1. The amount reported for ending inventory is incorrect because management used a simple average instead of weighted-average to calculate the unit cost of inventory for the year.
2. The amount reported for ending inventory cannot be determined with the information given because the amount depends on which of the 1,000 units were assumed to be sold.
3. The amount reported for ending inventory is incorrect because the unit cost of ending inventory should be the average cost of the last 300 units purchased.
4. The amount reported for ending inventory is correct.

Mike and Maria are married and earned salaries this year of $64,000 and $12,000, respectively. In addition to their salaries, they received interest of $350 from municipal bonds and $500 from corporate bonds. Mike and Maria also paid $2,500 of qualifying moving expenses, and Maria paid alimony to a prior spouse in the amount of $1,500. Mike and Maria have a 10-year-old son, Matthew, who lived with them throughout the entire year. Thus, Mike and Maria are allowed to claim a $1,000 child tax credit for Matthew. Mike and Maria paid $6,000 of expenditures that qualify as itemized deductions and they had a total of $5,500 in federal income taxes withheld from their paychecks during the course of the year.(USE 2017 tax schedule.)

An asset with the first cost of $100,000 is depreciated over a 5-year period. It is expected to have a $10,000 salvage value at the end of 5 years.

(1) Using the straight-line method, what is the net book value at the end of year 2?

(2) Using the sum of years digit method, what is the depreciation expense for year 1?

(3) Using the double-declining balance method, what is the depreciation expense for year 3?
