The answer is Canada answer from many resources
No hypothesis test is 100% certain. Because the test is based on probabilities, there is always a chance of making an incorrect conclusion. When you do a hypothesis test, two types of errors are possible: type I and type II. The risks of these two errors are inversely related and determined by the level of significance and the power for the test. Therefore, you should determine which error has more severe consequences for your situation before you define their risks.Type I errorWhen the null hypothesis is true and you reject it, you make a type I error. The probability of making a type I error is α, which is the level of significance you set for your hypothesis test. An α of 0.05 indicates that you are willing to accept a 5% chance that you are wrong when you reject the null hypothesis. To lower this risk, you must use a lower value for α. However, using a lower value for alpha means that you will be less likely to detect a true difference if one really exists.Type II errorWhen the null hypothesis is false and you fail to reject it, you make a type II error. The probability of making a type II error is β, which depends on the power of the test. You can decrease your risk of committing a type II error by ensuring your test has enough power. You can do this by ensuring your sample size is large enough to detect a practical difference when one truly exists.
Answer:
The knowledge about interior of the earth is obtained through direct sources and indirect sources. Direct sources include rock materials from mining areas and molten magma from volcanic eruptions. Besides, scientists are working on “Deep Ocean drilling Project” and “Integrated Ocean Drilling Project”

Answer:
High tides and will get balanced if the mas were same.
Explanation:
- If the earth would be doubled in size of the diameter and be around the 16,000m lies the planet mas would increase about eight times and thus the forces of the gravity would also be double and would be twice as long and large thus moon effects on the one side of the planet would be larger and produce more and high tides.
- But if the mass of the moon would be the same as that of the earth then the mass would be balanced by the different values of the weights. As there is a large force on a large mass and visa versa
