As the degrees of freedom increase, the t distribution approaches the "normal distribution".
<h3>
What is normal distribution?</h3>
For independent, random variables, the normal distribution, often referred as the Gaussian distribution, represents the most significant probability distribution in statistics. Most people are familiar with the bell-shaped curve found in statistical reports.
Some key features regarding the normal distribution are-
- A normal distribution is a probability distribution that is symmetrical around the mean, with most observations clustering around the central peak and probabilities tapering off equally in both directions.
- Data points in both distribution tails are similarly uncommon.
- Whereas the normal distribution appears symmetrical, it is not the only symmetrical distribution.
- The Student's t, Cauchy, & logistic distributions, for example, are symmetric.
- The normal distribution, like any other probability distribution, defines the how values of a variable is distributed.
- Because it accurately captures the range of values for many natural occurrences, it's the most essential probability distribution in statistics.

Stress refers to a feeling of emotional or physical tension. This feeling usually comes from an event or an idea that makes us feel frustrated, angry or nervous. These pressures can force our bodies to react in particular ways, usually resulting in damage over long periods of time. However, stress can also be dependent on culture.
Different cultures find different situations stressful. For example, in some cultures, social acceptance or status is a constant source of stress, while in others, differences among individuals and lack of acceptance are not considered major problems.
As an example, we can look at the cultures of Japan and the United States.
In Japanese culture, social standing is an important source of stress. Japanese people feel a responsibility towards the rest of their community, which can lead them to prioritize others before themselves. The needs of the community and the approval of others can be important sources of stress.
On the other hand, in American culture, the individual tends to be prioritized. This means that Americans tend to feel more stressed when faced with personal problems, such as lack of individual success or prestige.This stems from a lack of personal recognition, rather than a sense of commitment or responsibility towards others.
Answer:
Reductions in Child Mortality. ...
Vaccine-Preventable Diseases. ...
Access to Safe Water and Sanitation. ...
Malaria Prevention and Control.
Explanation:
The average life expectancy of a child born in the U.S. in 1900 was 50 years. By 2010, this number had increased 60% to 80 years.1 Biomedical, epidemiological, and behavioral research combined with public policy played a major role in this gain. Below are major public health milestones of the last 100 years
Answer:
The difference between these two journalists's behavior to the same stress depends on various variables and factors however the most probable reason is:
This first journalist has reached his or her stress tolerance workload become too much to handle that leads to the job burnout such as exhaustion and sickness and fatigued and despondent. The other journalist is experiencing eustress that motivates individuals to work harder and is an incentive to get the work done.
