<em>Answer:</em>
<em>The distribution of a sample mean tends to be skewed to the right or left. </em><em> </em>
<em>Explanation:</em>
<em>The sampling distribution</em><em> is described as one of the probability distribution related to a statistic discovered via an entirely large number of various samples that are being drawn from a particular population. However, the "sampling distribution" of a particular population refers to the distribution of distinct frequencies related to a range of various outcomes that can occur towards the statistics of a given population. </em>
Answer:
GLACIAL DEPOSITS
Today, glacial deposits formed during the Permo-Carboniferous glaciation (about 300 million years ago) are found in Antarctica, Africa, South America, India and Australia. If the continents haven’t moved, then this would suggest an ice sheet extended from the south pole to the equator at this time - which is unlikely as the UK at this time was also close to the equator and has extensive coal and limestone deposits. If the continents of the southern hemisphere are re-assembled near the south pole, then the Permo-Carboniferous ice sheet assumes a much more reasonable size.
More evidence comes from glacial striations – scratches on the bedrock made by blocks of rock embedded in the ice as the glacier moves. These show the direction of the glacier, and suggest the ice flowed from a single central point.
The primary characteristic of Archaic cultures is a change in subsistence and lifestyle; their Paleo-Indian predecessors were highly nomadic, specialized hunters and gatherers who relied on a few species of wild plants and game, but Archaic peoples lived in larger groups, were sedentary for part of the year
