Question

Differentiate between type I and type II and how each might be controlled. Identify which error researchers primarily control for and explain why. (2 points)

Answer #1

What is the difference between Type 1 and Type II error? How is
Type I error related to α? How is Type II error related to
power?

Regarding the definition of Type I and Type II error, which of
the following is correct?
A) Type I error: Fail to reject the null hypothesis when it is
actually false.
B) Type II error: Reject the null hypothesis when it is actually
true.
C) The probability of Type I error is equal to the significance
level.
D) Neither Type I error nor Type II error can be controlled by
the experimenter.

Identify the type I error and the type II error that corresponds
to the given hypothesis. The proportion of settled medical
malpractice suits is 0.34

a) What is difference between a Type I error and a Type II error
in detail?

Identify the type I error and the type II error for a hypothesis
test of the indicated claim.
The percentage of
households with more than 1households with more than 1
pet
is
greater
than
sixtyfive percent
Identify the type I error. Choose the correct answer below.
A. Reject the null hypothesis that the percentage of
households with more than 1households with more than 1
pet is greater than 65 %
when it is actually true.
B.
Fail to reject the...

Is it worse to make a Type I or a Type II error? [Think
carefully before you answer.] Explain what it means, and
why.

IF IN AN HYPOTHESIS TEST I FAIL TO REJECT Ho, WHAT TYPE
OF ERROR MIGHT I HAVE MADE.
A. TYPE I
B. TYPE II
C. TYPE 5
D. SUBTRACTION ERROR.

Identify the type I error and the type II error that correspond
to the given hypothesis.
The percentage of households with more than 1households with
more than 1 pet is less than 65%.
Identify the type I error. Choose the correct answer below.
A.
Fail to reject the null hypothesis that the percentage of
households with more than 1 households with more than 1 pet is
equal to 65%
when that percentage is actually less than 65 %.
B.
Fail...

determine whether the outcome is a Type I error, a type II
error, or a correct decision, explain your answer. A test is made
of H0:u=18 versus H1:unot equal 18. the true value of u is 18 and
H0 is not rejected

State the hypotheses. Describe a Type I and Type II error in the
context of the problem and a consequence of each. Determine which
type is most serious. State whether alpha should be set high or low
(based on whether or not you feel a Type I error is the most
serious or not). A manufacturer is testing light bulbs in the
quality assurance lab. Each bulb receives a durability score. 100
bulbs from each production run are analyzed. If...
