How is a marketing -oriented firm different from a production-oriented firm or a sales-oriented firm?

dedylja [7]

Marketing-oriented firms focus more on what the market needs above every other aspects.

<h3>What is a Marketing-oriented Firm?</h3>

Marketing-oriented firms can be described as firms that major in identifying the needs and wants of customers and then creating specific products that are designed to meet the wants of such customers. One of the important elements of marketing-oriented firms is to ensure there is a demand for whatever products or services they offer.

Some examples of marketing-oriented firms are:

Apple
Coca-Cola
Amazon

<h3>What is a Product-oriented Firm or a Sales-oriented Firm?</h3>

A product-oriented firm focus more resources on and focus on researching and developing quality products rather than focusing more on the market to discover the wants of customers.

Sales-oriented firm tend to focus more on developing its sales force that will promote their products and services.

<h3>How Marketing-Oriented Firms are Different from the Product-oriented or Sales-oriented Firms?</h3>

Marketing-oriented firms stand out and are different from the other two types of firms because they focus more on what the market needs above every other aspects.

The president of a small manufacturing firm is concerned about the continual increase in manufacturing costs over the past sever

mrs_skeptik [129]

Answer:

The answers to the question are

(a) The time series plot is given as attached

(b) The parameters for the line that minimizes MSE for the time series are;

y-intercept, b₀ = 19.993

Slope, b₁ = 1.77

MSE = 19.44

T $_t$ = 19.993 + 1.774·t

(c) The average cost increase that the firm is realizing per year is $ 1.77

(d) The estimate of the cost/unit for next year is $35.96.

Step-by-step explanation:

(a) Using the provided data, the time series plot is given as attached

(b) Given hat the y-intercept, = b₀

Slope = b₁

Therefore the linear trend forecast equation is given s

T $_t$ = b₀ + b₁·t

The linear trend line slope is given as

b₁ = $\frac{\Sigma^n_{t=1}(t-\overline{\rm t)}(Y_t-\overline{\rm Y)}}{\Sigma^n_{t=1}(t-\overline{\rm t} )^2}$

b₀ = $\overline{\rm Y}$ - b₁· $\overline{\rm t}$

Where:

Y $_t$ = Time series plot value at t

n = Time period number

$\overline{\rm Y}$ = Time series data average value and

$\overline{\rm t}$ = Average time, t

Therefore, $\overline{\rm t}$ = $\frac{\Sigma^n _{t=1} t}{n} = \frac{36}{8} =4.5$

$\overline{\rm t}$ = 4.5

$\overline{\rm Y}$ = $\frac{\Sigma^n _{t=1} Y_t}{n} = \frac{223.8}{8} =27.975$

$\overline{\rm Y}$ = 27.975

Therefore the linear trend line equation T $_t$ , is

b₁ = $\frac{\Sigma^n_{t=1}(t-\overline{\rm t)}(Y_t-\overline{\rm Y)}}{\Sigma^n_{t=1}(t-\overline{\rm t} )^2}$ = $= \frac{74.5}{42}$ = 1.774

b₀ = $\overline{\rm Y}$ - b₁· $\overline{\rm t}$ = 27.975 - 1.774×4.5 = 19.993

Therefore the trend equation for the linear trend is

T $_t$ = 19.993 + 1.774·t

MSE = $\frac{1}{2} \Sigma(Y-\overline{\rm Y)^ }^2$ = $\frac{155.495}{8}$ = 19.44

(c) From the linear trend equation, the average is given as the slope of the curve or b₁ which is equal to 1.774

Therefore the average cost increase that the firm has been realizing per year is $ 1.77

(b) From the equation of the future trend, we have when y = 9

T $_t$ is given as

T $_t$ = 19.993 + 1.774×9 = 35.96

The cost/unit for 9th year is $35.96

Ask Your Teacher Consider a binomial random variable with n = 5 and p = 0.8. Let x be the number of successes in the sample. Eva

Readme [11.4K]

Answer:

0.942 is the required probability.

Step-by-step explanation:

We are given the following in the question:

x is a binomial random variable with n = 5 and p = 0.8.

Then,

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

We have to evaluate:

$P(x \geq 3) = P(x = 3) + P(x = 4) +P(x=5)\\\\= \binom{5}{3}(0.8)^3(1-0.8)^2 +\binom{5}{4}(0.8)^4(1-0.8)^1 +\binom{5}{5}(0.8)^5(1-0.8)^0\\\\= 0.2048 +0.4096+0.3276=0.942$

0.942 is the required probability.
