Answer: Independent Samples t-test
Explanation:
The independent samples t test, also called an unpaired samples t test, is used to compare two sets of data from samples that are independent.
This experiment compares two sets of data, the grades from the group of learners that took the course in the old format and the group that took it in the new format, to see if the grades differ depending on the format of the course.
The one sample t test wouldn´t be correct because it´s used to compare one result with an expected value. And the paired t test wouldn´t be correct because it´s used to compare related observations, such as test scores from a test taken at different hours of the day.
Alfred Wegener had two flaws with his initial hypothesis. They are as follows:
i) Gravitational forces of the moon and sun, and tidal forces act as the mechanism to move the continents across the globe.
ii) Larger and sturdier continents broke through thinner oceanic crust like boat cutting through a thin layer of sea ice.
<u>Explanation</u>:
Alfred Lothar Wegener was a great meteorologist and German polar researcher. He was commonly known for his <u>“theory of continental drift”.
</u>
In this theory, they proposed an idea that the continents were slowly drifting around the Earth. Many researchers objected his view. But he provided many evidence to support his continental drift hypothesis.
Some of the evidences are: Continental jigsaw puzzle, Fossils match across the seas, Rock types and geologic features and Ancient Climates.
