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.

According to the graph, the prediction on the future is that there will be c. resource depletion.
<h3>What does the graph show?</h3>
The graph shows that as time goes on, humanity will demand more and more hectares of forest.
This will lead to forests eventually being wiped out after around 700 years which points to resource depletion.

The correct answer is e. Java.
All of the Neanderthal skeletal remains that are found so far are from Europe and the Middle East (Western Asia). Java is an Indonesian island in Southeast Asia, and in here there's no evidence found of Neanderthals living in this part of the world, nor anywhere in close proximity.
Answer: I guess the explanation is the answer
Explanation: An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction.
