Explain Type I error. Use an example if needed. Errors in Hypothesis Testing: In the context of statistics, a hypothesis testing is usually carried out to see whether the statistical results for a small sample can be applied to the corresponding population. This testing is useful for inferential...
A fire alarm provides a good analogy for the types of hypothesis testing errors. Preferably, the alarm rings when there is a fire and does not ring in the absence of a fire. However, if the alarm rings when there is no fire, it is a false positive, or a Type I error in statistical...
In more statistically accurate terms,type 2 errors happen when the null hypothesis is false and you subsequently fail to reject it. If the probability of making a type 1 error is determined by “α”, the probability of a type 2 error is “β”. Beta depends on the power of the test ...
Type I ErrorIn hypothesis testing we have two types of error, such as the:Type I Error: It is the rejection of the null hypothesis when the null hypothesis is true. It is also known as “false positive”. For example, consider an innocent person that is convicted. Type I Error: It ...

The first type of error in hypothesis testing refers to:A.Reject the null hypothesis if true.B.Reject the alternative hypothesis if it is false.C.Reject the alternative hypothesis if it is true.D.Reject the null hypothesis if it is false.的答案是什么
Type I and type II errors occur during statistical hypothesis testing. While the type I error (a false positive) rejects a null hypothesis when it is, in fact, correct, the type II error (a false negative) fails to reject a false null hypothesis. For example, a type I error would conv...
For example, a test for a disease may report a negative result when the patient is infected. This is a type II error because we accept the conclusion of the test as negative, even though it is incorrect. A type II error can be contrasted with atype I errorin that the latter is the...
