Answer:

N = 3,120 (Approx)

Explanation:

Given:

z- score for 99% confidence = 2.58

Proportion (P) = 75% = 75 / 100 = 0.75

E = 2% = 0.02

Q = 1 - P = 1 - 0.75 = 0.25

Computation:

N = (Z/E)^2 \times pq

N = (2.58/0.02)^2 \times (0.75 \ times 0.25)

N = (129)^2 \times (0.1875)

N = (16,641) \times (0.1875)

N = 3,120.1875

Therefore, N = 3,120 (Approx).

Richard, a researcher, is of the opinion that organizations should empower employees, and suggests this should be done by design
USPshnik [31]

Answer:

a. Self-managing teams are highly involved in decision making

Explanation:

Option A validates Richards argument

A self-managed team is a group of employees responsible and accountable for all or most aspects of producing a product or delivering a service. Self managed teams can work without being supervised. Therefore they are highly involved in decision making. Such teams are important due to the motivation they give to employees to take ownership. When these employees are allowed to make decisions, they enter a new level of engagement and participation.

Dmitriy789 [7]

Answer:

Collectivism

Explanation:

In China is found a highly collectivist culture where individual members of the society act in the interest of the groups and not to satisfy their own personal interests. The unity established by this culture helps them collaborate effectively in large –scale projects and contribute their best towards attaining a better outcome.

The collectivism practiced in china is different from what is seen in most western parts of the world where individuals, rather than groups, are at the center of activities.

All of the following are ways to calculate different versions of ROI​ except: A. Return on sales x investment turnover B. Income
Virty [35]

Answer:

The answer is D

Explanation:

The formula - Revenues​ / Total Assets is not one of the ways to calculate Return on Investment (ROI)

Return on Investment (ROI) is a ratio

net profit to cost of investment(total money invested the project or compnay)

The numerator must be profit while the denominator must be related to cost of Investment.

In all of the options, it is only option D that has revenue(sales) as the numerator which makes it automatically wrong.

Productive efficiency focuses on the cost of production while allocative efficiency focuses on the distribution of the products.

In economics, the efficiency or productivity of a business is classified into two types:

  • Productive efficiency.
  • Allocative efficiency.

These two types of efficiency focus on different aspects of production and selling goods and services.

Productive efficiency: This type implies producing goods at the lowest cost possible. This means:

  • Avoiding unnecessary costs.
  • Controlling costs when the number of units increases.

Allocative efficiency: This type implies selling or allocating the products in society. This means:

  • Considering the maximum amount the customer can pay for a product (marginal benefit).
  • Making the cost of production equal to the marginal benefit.

Note: This question is incomplete because the statements that need to be classified are not provided; due to this, I answered the question based on general knowledge.
