Answer:
The answer is- Test of two proportions
Explanation:
A test for two proportions is used to compare two proportions in order to see if they are the same. it is used when comparing the percentages of two groups. Like in the question, the marriage counselor is checking to see if the percentage of communicative couples whose marriage ended separation or divorce was greater than the percentage of non-communicative couples whose marriage ended in separation or differences.
The two different proportions are the communicative and non-communicative couples.
Answer:
Confucianism teaches how to act toward others; Daoism teaches how to act toward oneself and nature.
Explanation:
Confucianism and Daoism are two of the most popular philosophies or ideologies that are followed even today, not only by the number of followers native to Asia, but also by many other people around the world.
While they have some religious elements in common, the two philosophies seem to contradict each other at first sight. However, seeing it differently, between these two ideologies, methodologies of human thought seem to be intertwined with respect to everything; which leads to certain defined codes of conduct.
In spite of everything, the two philosophies differ in some things. Above all, Confucianism is more earthly. As such, it focuses on the social aspect of man and his daily life. As Confucius said, philosophy is inherently the social creature that has the ability to be good. You become someone superior if you behave in the way society expects to keep in harmony.
Daoism is different, because it goes beyond this world. The main idea of this philosophy is to embrace the Dao (the greatest reality that is composed of the universe and everything else). It also focuses on the person's relationship with himself to achieve inner harmony. Therefore, it is well to say that in Confucianism the person achieves self-improvement by relating to his immediate external environment, while Daoism proposes that this overcoming is achieved from oneself; that is, internally.
Answer:
The rock is 3.75 billion years ago.
Explanation:
Given that:
Half life = 1.25 billion years
1 billion years = 10⁹ years
So,
Half life = 1.25 × 10⁹ years

Where, k is rate constant
So,


The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,





So,
<u>The rock is 3.75 billion years ago.</u>
Answer:
Observational study
Explanation:
An observational study is a type of study in which individuals are observed and certain measures are measured but there's no intend to affect the actual outcome. In other words, no treatment is given to the individuals and there's no intervention done by the researcher.
In this example, the study aims to evaluate the percent of adults whose right cerebral hemisphere is larger than the right hemisphere. 20 people come and have their brains scanned. Then, the scan is analyzed to identify which hemisphere is larger.
In this study, we can see how <u>individual's brains were observed and some measures were taken but there was no treatment given to them</u> (the researchers were only interested in knowing which hemisphere was bigger).
Thus, this is an example of observational study.
Answer:A CORE CULTURE
Explanation:
Core culture refers to values of an organization and this is found in Edgar Schein's model of Organizational culture.
Core culture is made up of three P's from the five P's which can be best depicted in a formula as: Core culture =Purpose+Philosophy+priorities
The organization needs to have a crucial purpose, a diffrent and long lasting Philosophy and strategic priorities. These are the ethos that will stabilize the organization and they need to be well known in the organization. They will act as a guidance to employees within work and out of work. These principles and values are characteristics that defines the organization through its employees even in the outer world. Which set them apart from other companies.
