(6 points) Life rating in Greece. Greece faced a severe economic crisis since the end of 2009. Suppose a Gallup poll surveyed 1,

000 randomly sampled Greeks in 2011 and found that 24% of them said they would rate their lives poorly enough to be considered "suffering." Round all answers to four decimal places. 1. What is the population parameter of interest? A. The score on the survey that corresponds to suffering. B. The actual proportion of Greeks who believe they are suffering. C. The 25% of Greeks in the sample who believe they are suffering. D. All the people who live in Greece. 2. What is the value of the point estimate of this parameter? 3. Construct a 95% confidence interval for the proportion of Greeks who are "suffering." ( , ) 4. If we decided to use a higher confidence level, the confidence interval would be: A. wider B. narrower C. stay the same 5. If we used the same confidence level with a larger sample, the confidence interval would be: A. wider B. narrower C. stay the same

Answer:

1. B. The actual percentage of Greeks who feel they are suffering.

2. This represents the portion of Greeks sampled, thus p = 0.25

3. n = 250 phat - 25% — 0.25 z score - 5%/2 —  2.5 on each end — z = 1.9 se - apply formula -.0470.25 +/- 1.9 x.027+:.3675 -:.1325.

4. A. broader

5. B. slimmer

Explanation:

In this inquiry, it is vital to evaluate the real population of Greeks believing themselves to be extremely poor and suffering. This information will inform proper sampling. Furthermore, it was identified from the sample that the parameter point estimate stands at approximately 25%, and any change in sample size or confidence level will impact the interval.

There is a debate about whether sterile hypodermic needles should be passed out free of charge in cities with high drug use,. Pr
Scilla [3833]

Answer:

a) This policy would be advantageous if the demand for sterile needles has elastic characteristics and the cross-price elasticity of demand linking drugs and sterile needles is high and

positive.

b) This policy would be unfavorable if the demand for sterile needles is characterized as inelastic while the cross-price elasticity between drugs and needles is high and

negative.

Explanation:

a) Under what conditions is this policy viewed as beneficial?

This policy is advantageous when the demand for sterile needles is elastic and the corresponding cross-price elasticity with drugs shows a positive and high relationship.

The elastic demand for sterile needles indicates that the quantity demanded increases more significantly in response to price changes.

The positive cross-price elasticity suggests that as the price of needles decreases, the demand for drugs decreases, assuming they are substitutes. Therefore, as the price of sterile needles approaches zero, the

demand for drugs diminishes.

b) Under what conditions is this policy seen negatively?

This policy turns unfavorable when the demand for sterile needles is inelastic and the cross-price elasticity relating drugs to needles is high and

negative.

An inelastic demand for sterile needles suggests the quantity demanded does not increase much with price reductions.

A negative cross-price elasticity indicates that the two products, drugs and sterile needles, are complements. Thus, as the price of sterile needles drops to zero, the demand for drugs rises.

Blake eats two bags of potato chips each day. Blake's hourly wage increases from $9 to $15, and he decides to stop eating generi
Mariulka [3825]

Answer:

-4 units

Explanation:

Applying the midpoint method, Blake's income elasticity of demand for generic potato chips is determined by multiplying the change in demand (D) by his average income (I), then dividing by the product of the change in income and average demand:

E=\frac{\Delta D}{\Delta I}*\frac{I_{avg}}{D_avg}\\E=\frac{0-2}{15-9}*\frac{\frac{9+15}{2}}{\frac{2+0}{2} }\\E=-4\ units

Thus, Blake's income elasticity of demand equals -4 units.

Nady [3600]

Answer:

resource allocation

Explanation:

Based on my findings on various business strategies, I can conclude that this scenario exemplifies the resource allocation aspect of a strategy. It represents how a company optimally uses its resources throughout the organization by identifying new opportunities for resources that have not been fully utilized. This is occurring here as funds that are currently underutilized are being redirected into the shoe business.

I trust this clarifies your question. Should you have further inquiries, feel free to ask.

harina [3808]
The depreciable life of an asset is crucial for the financial manager. Generally, a shorter depreciable life is advantageous, as it leads to quicker cash flow circulation. This concept of depreciation allows for the expense of financial or intangible resources to be allocated over their useful lives. It indicates the extent to which an asset's value diminishes over time. For both taxation and accounting, long-term assets can be depreciated, and the duration allocated to these assets significantly influences the cash flow. Hence, shorter depreciable lives are more favorable compared to longer ones due to the expedited influx of cash for finance managers.

INCOME STATEMENT Little Books Inc. recently reported $3 million of net income. Its EBIT was $6 million, and its tax rate was 40%
Katen [3525]

Answer:

The interest amounts to $1,000,000.

Explanation:

The standard format of an income statement includes:

Revenue/Sales (+)

Cost of Goods Sold (COGS) (-)

=Gross Profit

Marketing, Advertising, and Promotion Expenses (-)

General and Administrative (G&A) Expenses (-)

=EBITDA

Depreciation & Amortization Expense (-)

=Operating Income or EBIT

Interest (-)

Other Expenses (-)

=EBT (Pre-Tax Income)

Income Taxes (-)

=Net Income

For this case:

EBIT equals $6,000,000.

The interest is to be determined.

Tax is calculated as 0.40.

EBITDA stands at $3,000,000.

The interest formula is: interest = [EBITDA / (1 - tax)] - EBIT

Substituting values, interest = 3000000 / 0.60 - 6000000 = -$1,000,000.

With EBIT at 6 million, the interest is $1 million, and the tax amounts to 2 million (calculated as (EBIT - interest) * 0.40).

Thus, the net income is $3 million.
