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.

Answer:A weak immune system
Explanation:
When people get older their immune system becomes weak including the function of the T cells which are cells responsible for fighting infections.
This means it becomes hard to recover from a flue when someone get sick and they are always prone to sickness since their immune system no longer has the power to fight infections.

Answer:
Well, it's like with Suffragettes, a group of women fighting for the rights of women, well it's not completely like it, however, with the fight for women's rights, society had created a certain mindset, that women were a weaker sex, and that all and any of their value came with how the men saw them, they had no rights and they were thought of to need men. With Slavery, society had created a certain mind set that most people no longer hold, they believed that people of colour were lower than them, that they didn't deserve to have rights. The dehumanized them like they did with people from India, and as they dehumanized the slaves, it was easier for them to be able to treat them so poorly. Society had created this view and everyone else agreed. It was to help themselves and take over. Not to mention that Glory, Gold and Land was so important back then, people really didn't care about others, if they felt like someone wasn't of their status, they treated them poorly. Just like in Harry Potter, the purebloods had all gotten this ideology that they were better than anyone less than them, they taught their children and acted on their beliefs.
