By weighing the responses of diverse groups, polling companies attempt to overcome the challenges of assembling a sample of respondents that accurately reflects the entire population.

<h3>What is a survey research ?</h3>

The definition of survey research is "the gathering of data from a sample of people through their responses to questions". A variety of techniques can be used to find participants, gather data, and instrument the study in this type of research. Both quantitative and qualitative research methods can be applied to surveys.

Historically, large-scale population-based data gathering has been a component of survey research. This kind of survey research's main goal was to quickly gather information on the features of a wide sample of interesting people. Consumer feedback surveys and large census surveys that gather data on demographic and personal characteristics are two prominent examples. These questionnaires, which were frequently mailed out, were designed to gather information for programs or products aimed at a specific population or group or to describe the demographic characteristics of individuals.

Alenkinab [10]

Answer:

$10,000

Explanation:

Depreciation of an asset is the systematic allocation of estimated cost to an asset over time. It is added over the years to get the accumulated depreciation that is netted off the cost to get the net book value.

It is given as

Depreciation = (Cost - Salvage value)/Estimated useful life

Depreciation expense for Year 1 (the first year of the asset's life) under the straight-line method would be

= ( $60,000 - $10,000 ) / 5

= $50,000/5

= $10,000

What is the stock price per share for a stock that has a required return of 16%, an expected dividend $2.7 per share, and a cons
Anit [1.1K]

Answer:

Price of stock = $49.5

Explanation:

<em>The Dividend Valuation Model(DVM) is a technique used to value the worth of an asset. According to this model, the value of an asset is the sum of the present values of the future cash flows would that arise from the asset discounted at the required rate of return. </em>

If dividend is expected to grow at a given rate , the value of a share is calculated using the formula below:  

Price of stock=Do (1+g)/(k-g)  

Do - dividend in the following year, K- requited rate of return , g- growth rate  

DATA:

D0- 2.7

g- 10%

K- 16%

Price of stock = ( 2.7×1.1)/(0.16-0.1) = 49.5

Price of stock = $49.5

MAXImum [283]

Answer:

Answer for the question:

During the beginning of the 21st century, the growth in computer sales declined for the first time in almost two decades. As a result, PC makers dramatically reduced their orders of computer chips from Intel and other vendors. In general, the environment in which computer manufacturers operate is very uncertain; how should we expect this feature of the market to affect the length of contracts between computer manufacturers and their hardware manufacturers?

Suppose you are currently invested 100% in U.S. stocks and you CANNOT short: a.Find the portfolio that maximizes expected return
Volgvan

Answer:

Part a: The portfolio which maximizes the expected return is in the attached file.

Part b:The portfolio's expected rate of return is 11.20% and the weight is 100% for US only.

Explanation:

As the question is incomplete and the data is not available, thus the complete question is found as attached with the solution.

The Sharpe rate is given as

S_a=\frac{E_a-E_r}{\sigma}

Where

  1. E_a is the estimated rate of return for a value
  2. E_r is the risk free rate of return
  3. σ is the standard deviation of the investment.

The portfolio variance is given as

\sigma^2_{portfolio}=\sum_{i}^{n}{\sigma_i^2w_i^2}+\sum_{i}^{n(n-1)/2}{cv_i}

Where

  1. σ is the standard deviation of the investment.
  2. w is the weighted value of the investment
  3. cv is the covariance term

Portfolio standard deviation is given as

\sigma_{portfolio}=\sqrt{\sigma^2_{portfolio}}

Expected rate is given as

E_{rate of return}=\sum_{i=1}^{n}{E_a_i\times w_i}

Now the Sharp value is calculated as above.

Now the values as given in the excel sheet are added in the attached excel sheet,  following formulas are used to calculate various values

Sharpe ratio is calculated using =(B6-J3)/C6

Portfolio variance is calculated using (=B13^2*C6^2+B14^2*C7^2+B15^2*C8^2+B16^2*C9^2+2*B13*B14*C6*C7*D7+2*B13*B15*C6*C8*D8+2*B13*B16*C6*C9*D9+2*B14*B15*C7*C8*E8+2*B14*B16*C7*C9*E9+2*B15*B16*C8*C9*F9)

Portfolio standard deviation is SQRT(Variance)

Expected return is calculated using =B13*B6+B14*B7+B15*B8+B16*B9

Sharpe is calculated using =(B23-$J$3)/B22

Part a:

The portfolio which maximizes the expected return is in the attached file.

Part b:

The portfolio's expected rate of return is 11.20% and the weight is 100% for US only.

katrin2010 [14]

Answer:

The answer to this question is option C  Real Business Cycle theory

Explanation:

The Real business cycle theory is the theory that views hocks to tastes (workers' willingness to work, for example) and technology (productivity) as the major driving forces behind short-run fluctuations in the business cycle because these shocks lead to substantial short-run fluctuations in the natural rate of output.  

Real business cycle models state that macroeconomic fluctuations in the economy can be largely explained by technological shocks and changes in productivity. These changes in technological growth affect the decisions of firms on investment and workers (labour supply)

Hence the answer is option C  Real Business Cycle theory
