Determine whether the outcome is a Type I error, a Type II error, or a correct decision.
A test is made of H0: μ = 25 versus H1: μ ≠ 25. The true value of μ is 25 and H0 is rejected.
Homework Answers
Answer #1
In this problem we test 
VS 
.
By the definition of a type -1 error,we reject 
when it is true. In the question
is rejected when it is true,i.e, when 
.
Hence a type 1 error has been committed.

For the given significance test, explain the meaning of a Type I
error, a Type II error, or a correct decision as specified. A
health insurer has determined that the "reasonable and customary"
fee for a certain medical procedure is $1200. They suspect that the
average fee charged by one particular clinic for this procedure is
higher than $1200. The insurer performs a significance test to
determine whether their suspicion is correct using α = 0.05. The
hypotheses are:

A test of H0: μ = 60 versus H1: μ ≠ 60 is performed using a
significance level of 0.01. The P-value is 0.033. If the true value
of μ is 53, does the conclusion result in a Type I error, a Type II
error, or a correct decision?

Type I error: Washers used in a certain
application are supposed to have a thickness of 2 millimeters. A
quality control engineer measures the thicknesses for a sample of
washers and tests H0: μ = 2 versus
H1: μ ≠ 2.
