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:
The sea’s natural splendor.
Explanation:
E. M. Berens' <em>The Myths and Legends of Ancient Greece and Rome</em> presents an interesting insight into the world of the myths and legends that we know only through stories and fantasy movies. And in this text, he also provides an insight into the underwater home of the sea god Poseidon.
And in the excerpt, he describes the place as <em>"surrounded on all sides by wide fields, where there were whole groves of dark purple coralline, and tufts of beautiful scarlet-leaved plants, and sea-anemones of every tint"</em>. Moreover, there were<em> "bright, pinky sea-weeds, mosses of all hues and shades, and tall grasses,[....] fish of various kinds playfully darted in and out...</em>". Added to that <em>"fairy-like region"</em>, there was no need or shortage of light which is provided by<em> "the glow-worms of the deep"</em>. All these details <em><u>depict the sea's splendor and the ethereal-like place of the sea kingdom.
