In this problem, assume that the distribution of differences is
approximately normal. Note: For degrees of freedom
d.f. not in the Student's t table, use
the closest d.f. that is smaller. In
some situations, this choice of d.f. may increase
the P-value by a small amount and therefore produce a
slightly more "conservative" answer.
Are America's top chief executive officers (CEOs) really worth all
that money? One way to answer this question is to look at row
B, the annual company percentage increase in revenue,
versus row A, the CEO's annual percentage salary increase
in that same company. Suppose a random sample of companies yielded
the following data:
|
B: Percent increase for company |
26 | 25 | 27 | 18 | 6 | 4 | 21 | 37 |
| A: Percent
increase for CEO |
21 | 23 | 22 | 14 | −4 | 19 | 15 | 30 |
Do these data indicate that the population mean percentage increase in corporate revenue (row B) is different from the population mean percentage increase in CEO salary? Use a 5% level of significance. (Let d = B − A.)
What is the value of the sample test statistic? (Round your answer to three decimal places.)

Is fishing better from a boat or from the shore? Pyramid Lake is
located on the Paiute Indian Reservation in Nevada. Presidents,
movie stars, and people who just want to catch fish go to Pyramid
Lake for really large cutthroat trout. Let row B represent
hours per fish caught fishing from the shore, and let row
A represent hours per fish caught using a boat. The
following data are paired by month from October through April.
| Oct | Nov | Dec | Jan | Feb | March | April | |
| B: Shore | 1.4 | 1.8 | 2.0 | 3.2 | 3.9 | 3.6 | 3.3 |
| A: Boat | 1.3 | 1.3 | 1.6 | 2.2 | 3.3 | 3.0 | 3.8 |
Use a 1% level of significance to test if there is a difference in the population mean hours per fish caught using a boat compared with fishing from the shore. (Let d = B − A.)
What is the value of the sample test statistic? (Round your
answer to three decimal places.)

In Unit 3 we learn about recognition of revenue and expenses,
and the proper timing of their recording in the firm's accounting
records.
For those of us accustomed to thinking of revenue and expense occurring at the time payments are made and money changes hands, this may be a new and unfamiliar concept - but it is an important one.
Discuss the difference between accrual basis accounting and cash basis accounting. Please remember to create your submission in your own words. Feel free to include brief quotes from your sources (with citations) but do not copy and paste from the source material.

The following are five true-false questions. Write in whether true T or false F
In the short run, fixed costs are irrelevant in determining a firm's optimal level of output._______
In the short run, a competitive firm will not produce unless price is equal to average total costs.__________
If a purely competitive firm is producing a level of output greater than its profit-maximizing output, then marginal revenue is greater than marginal cost._________
Economic profit is the difference between total revenue and marginal revenue_________
Competitive firms are price takers largely because of intensive advertising by their competitors.__________

The data below are estimated for the project study of a certain business investment. If money is worth 12%, what is the difference in Present Worth between the alternatives?
Alternative A: The initial investment is $3,500, with an annual revenue of $1,900. Annual disbursement amounts to $645 with no salvage value at the end of its life, which is 4 years.
Alternative B: The initial investment is $5,000 with an annual revenue of $2,500. Annual disbursements is $1,383 with no salvage value at the end of its useful life, which is 8 years.
