In a random sample of six microwave​ ovens, the mean repair cost was ​$70.00 and the standard deviation was ​$12.00. Assume the variable is normally distributed and use a​ t-distribution to construct a 99​% confidence interval for the population mean u. What is the margin of error of u​?

The 99​% confidence interval for the population mean u is (_, _ ) ​(Round to two decimal places as​ needed.)

The margin of error is ___. ​(Round to two decimal places as​ needed.)

"A firm is considering purchasing a computer system.
-Cost of system is $188,000. The firm will pay for the computer system in year 0.
-Project life: 4 years
-Salvage value in year 0 (constant) dollars: $24,000
-Depreciation method: five-years MACRS
-Marginal income-tax rate = 40% (remains constant over time)
-Annual revenue = $141,000 (year-0 constant dollars)
-Annual expenses (not including depreciation) = $75,000 (year-0 constant dollars)
If the general inflation rate is 2.1% during the project period (which will affect all revenues, expenses, and the salvage value but not depreciation), determine the INFLATION-FREE IRR' of the computer system. Enter your answer as a percentage between 0 and 100."

What does a company’s weighted average cost of capital (WACC) represent?

Novak Company constructed a building at a cost of $2,684,000 and occupied it beginning in January 1998. It was estimated at that time that its life would be 40 years, with no salvage value.

In January 2018, a new roof was installed at a cost of $366,000, and it was estimated then that the building would have a useful life of 25 years from that date. The cost of the old roof was $195,200.

1) What entry should be made in 2018 to record the replacement of the roof? (If no entry is required, select "No entry" for the account titles and enter 0 for the amounts. Credit account titles are automatically indented when amount is entered. Do not indent manually.)

2) Prepare the entry in January 2018 to record the revision in the estimated life of the building, if necessary. (If no entry is required, select "No entry" for the account titles and enter 0 for the amounts. Credit account titles are automatically indented when amount is entered. Do not indent manually.)

3) What amount of depreciation should be charged for the year 2018?

-if a company's selling price for inventory falls below the cost of the inventory, the value of the inventory asset is adjusted. TRUE-FALSE

-Units of production is the most accurate depreciation method. TRUE - FALSE

-Double declining balance depreciation calculates depreciation expense by multiplying the cost less residual value by a depreciation rate. TRUE-FALSE

-Warranty costs are depreciated over the life of the warranty. TRUE - False

-Warranties offered by a company on its products are liabilities. TRUE - False

-Which of the following differences on a bank reconciliation does not require the company to make an adjusting journal entry? A: Bank service charges B: Interest earned C: EFT collection from a customer D: Outstanding checks.

What is meant by classifying a unit as an “investment center” vs. a “cost” or “profit” center? Discuss how each of the following tools, individually and/or collectively, can and should be used to evaluate managers of such “investment center” individual divisions of a large organization: ROI, EVA, and the Balanced Scorecard. (Hint: discuss how each works, what each helps ensure, what dysfunctional behaviors can result from its use, and how multiple approaches can help ensure behavior that aligns individual incentives with overall corporate strategy.)

a manager faces a problem of increasing cost in his company. This problem is specific to him. It might so happen that similar problems are faced by others in the industry. He tries to find the reasons for the rising cost and falling profit that might involve different areas of research. which types of research or mode will be necessary to solve the problem?
