The math is usually handled by software packages, but in the interest probability of type 2 error of completeness I will explain the calculation in more detail. A t-Test provides the probability what is the probability that a type i error will be made of making a Type I error (getting it wrong). If you are familiar with Hypothesis testing, then you can skip the next what is the probability of a type i error for this procedure section and go straight to t-Test hypothesis. Hypothesis TestingTo perform a hypothesis test, we start with two mutually exclusive hypotheses. Here’s an example: when someone is accused of a crime, we put them on trial to determine

their innocence or guilt. In this classic case, the two possibilities are the defendant is not guilty (innocent of the crime) or the defendant is guilty. This is classically written as…H0: Defendant is ← Null HypothesisH1: Defendant is Guilty ← Alternate HypothesisUnfortunately, our justice systems are not perfect. At times, we let the guilty go free and put the innocent in jail. The conclusion drawn can be different from the truth, and in these probability of a type 1 error symbol cases we have made an error. The table below has all four possibilities. Note that the columns represent the “True State of Nature” and reflect if the person is truly innocent or guilty. The rows represent the conclusion drawn by the judge or jury.Two of the four possible outcomes are correct. If the truth is they are innocent and the conclusion drawn is innocent, then no error has been made. If the truth is they are guilty and we conclude they are guilty, again no error. However, the other two possibilities result in an error.A Type I (read “Type one”) error is when the person is truly innocent but the jury finds them guilty. A Type II (read “Type two”) error is when a person is truly guilty but the jury finds him/her innocent. Many people find the distinction between the types of errors as unnecessary at first; perhaps we should just label them both as errors and get on with it. However, the distinction between the two types is extremely important. When we commit a Type I error, we put an innocent person in jail. When we commit a Type II error we let a guilty person go free. Which error is worse? The generally accepted position of society is that a Type I Error or putting an innocent per

Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Compute the probability of committing a type I and II error. up vote 0 down vote favorite I http://www.sigmazone.com/Clemens_HypothesisTestMath.htm hope that someone could help me with the following question of my textbook: One generates a number x from a uniform distribution on the interval [0,θ]. One decides to test H0 : θ = 2 against H1 : θ = 2 by rejecting H0 if x ≤0.1 or x ≥ 1.9. a. Compute the probability of committing a type I error. b. Compute the probability of committing a type II error if the true value of θ is 2.5 So my understanding of http://math.stackexchange.com/questions/1336367/compute-the-probability-of-committing-a-type-i-and-ii-error this question is that it would not reject if x is 1.9-2.0 or 0.0-0.1. The problem with this question is that I don't how to start. In my previous questions I had more information to solve this kind of questions. I think I understand what error type I and II mean. Type I means falsely rejected and type II falsely accepted. According to the book, the answers are a:0.1 and b:0.72 probability statistics hypothesis-testing share|cite|improve this question asked Jun 23 '15 at 15:34 Danique 1059 1 From context, it seems clear that $H_1: \theta \ne 2.$ –BruceET Jun 24 '15 at 0:06 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted For a type I error, you calculate the probability of a rejection under the assumption that the null hypothesis is true. So you find the density of $X$, call it $f_X$, under the assumption that $\theta=2$. Then the probability of a rejection is $$\int_0^{0.1} f_X(x) dx + \int_{1.9}^2 f_X(x) dx.$$ For a type II error, you calculate the probability of an acceptance under the assumption that the null hypothesis is false. In real problems you generally can't compute this, because usually knowing that the null hypothesis is false doesn't specify the distribution uniquely. But in your case they tell you what the actual value of $\theta$ is for this part of the problem, which lets you compute it. Specifically, the probability of an acceptance is $$\int_{0.1}^{1.9} f
