Answer:

two-stage area sampling

Explanation:

A two-stage area sampling is a type of sampling method that is employed when dealing with a large population that is being studied. In this type of sampling, two stages of the sampling process is involved. The first stage involves dividing the population under study into clusters, and then randomly selecting few clusters you want to focus on. The second stage involves, random selection of your subjects in each of the clusters that you have randomly selected out.

This is done to ensure, as much as possible, the population under study is adequately represented, especially when dealing with a large population size such a country, state, or region.

The type of sampling described in the question above is a two-stage area sampling.

Answer: . two-stage area

Explanation:

In two-stage specimen sampling, a simple random sample of specimen is selected and then a simple random sample is selected from the units in each sampled specimen. Two-stage sampling is used when the sizes of the specimens are large, making it difficult or expensive to observe all the units inside them.

Eric receives a portion of his income from his holdings of interest-bearing U.S. government bonds. The bonds offer a real intere
MArishka [77]

Solution :

Given :

The bonds offer a \text{real interest rate} of 4.5% per year

Tax rate = 10% = 0.10

Inflation rate = 2

\text{Nominal interest rate} = \text{real interest rate} + \text{inflation rate}

\text{Nominal interest rate} = 2 + 4.5

                                   = 6.5

\text{After tax nominal rate} = \text{Nominal interest rate} $\times (1-\text{tax rate})$

\text{After tax nominal interest rate} = $6.5 \times (1-0.10)$

                                                  $=6.5 \times 0.90$

                                                 = 5.85

After tax real interest rate = \text{after tax nominal rate} - \text{inflation rate}

                                           = 5.85 - 2.0

                                            = 3.85

\text{Inflation rate} = 7.0

\text{Real interest rate = 4.5}

\text{Nominal interest rate} = \text{real interest rate} + \text{inflation rate}

                                   = 7 + 4.5

                                  = 11.5

\text{After tax nominal interest rate} = \text{Nominal interest rate} $\times (1-\text{tax rate })$

                                                  $=11.5 \times (1 - 0.10)$

                                                  $=11.5 \times 0.90$

                                                = 10.35

\text{After tax nominal interest rate} = 11.5 x (1 - 0.10)

                                          = 11.5 x 0.90

                                         = 10.35

\text{After tax nominal interest rate} = \text{after tax nominal rate} - \text{inflation rate}

                                           = 10.35 - 7.0

                                          = 3.35

Putting all the value in table :

\text{Inflation rate}    Real interest  Nominal interest  After tax nominal  After tax  

                                  rate                rate               interest rate       interest rate

2.0                             4.5                  6.5                        5.85                   3.85

7.0                              4.5                11.5                         10.35                3.35

Comparing with the \text{higher inflation rate}, a \text{lower inflation rate} will increase the after after tax real interest rate when the government taxes nominal interest income. This tends to encourage saving, thereby increase the quantity of investment in the economy and the increase the economy's long-run growth rate.

Paha777 [63]

Answer:

B) Anticipatory Grief

Explanation:

As Khalid has found out that his friend Jason is terminally ill. This has made him feel sad and lonely at the thought of living life without his friend. Khalid's feelings best represent the concept of anticipatory grief which refers to the feeling of sadness and grief occurring before the actual happening of that loss. We become sad and emotional even before the actual happening of some incident. For example, when our dear friend is in hospital after a sever accident, then we start feeling this anticipatory grief that the chances are more that he will be dead soon so we feel more grief and sadness.

Pollution control equipment for a pulverized coal cyclone furnace is expected to cost $190,000 two years from now and another $1
alexandr1967 [171]

Answer:

$212,882.75

Explanation:

Cost from 2 years now = $190,000

Cost from 9 years now = $120,000

Interest rate = 9% Quarterly

Present Worth = Cost from 2 years now*[1/(1+interest/m)^nm] * Cost from 2 years now*[1/(1+interest/m)^nm]

Present Worth = 190,000*[1/(1+0.09/4)^2*4] + 120,000*[1/(1+0.09/4)^9*4]

Present Worth = 190,000*[1/(1.0225)^8] + 120,000*[1/(1.0225)^36]

Present Worth = 190,000*[1/1.19483] + 120,000*[1/2.22782]

Present Worth = 190,000*0.83693915 + 120,000*0.4488693

Present Worth = 159018.4385 + 53864.316

Present Worth = 212882.7545

Present Worth = $212,882.75

Thus, the amount to invest to cover these cost is $212,882.75

Developing, pricing, promoting, and delivering services is challenging because the quality of a service is often A. inseparable.
ZanzabumX [31]

Answer:

B. inconsistent

Explanation:

Marketing mix refers to a blend of those key marketing facets which increase consumer purchases.

Marketing mix is often emphasized by it's 4 P's i.e Product, Price, Place and Promotion.

Product is a bundle of attributes and utilities, price refers to the consideration received or receivable, promotion refers to sales promotion and advertisement channels while place refers to delivery or location where the buyer gets the product.

In case of a service, which is intangible unlike a product, it's quality and delivery is dependent upon it's provider. And since no two individuals can render exactly the same kind of service, owing to varied individual capabilities, the quality of a service is usually inconsistent or say unequal.

A survey of 50 retail stores revealed that the average price of a microwave was $375 with a sample standard deviation of $20. As
ohaa [14]

Answer:

True cost of the microwave is in 99% confidence interval: c. $323.40 to $426.60

Explanation:

Relevant data:

n=50\\\mu=375\\\sigma=20\\\alpha=0,001

As we want to know the 99% confidence interval, the significance level is:

(1-\alpha).100\%=99\%\\1-\alpha=0.99\\\alpha=0.01

We need to estimate a confidence interval by a two tailed normal bell. Then we have:

Z_{\alpha/2}=Z_{0.005}

The z-value for a probability of 0.005 in a normal standard distribution is 2.576

Confidence interval is given by;:

\=x\±Z_{\alpha/2}\sigma\\375\±Z_{\0.005}(20)\\375\±(2.58)(20)\\375\±51.60

375+51.60=426.60\\375-51.60=323.40

True cost of the microwave is in 99% confidence interval: c. $323.40 to $426.60
