Question

If one is making a two-tailed test and the value of the z test statistic is -11.12, a correct conclusion from this is

Group of answer choices:

do not reject HO

a type II error has been made.

reject HO

reject HO at the .05 level but not at the .01 level.

Answer #1

Answer: Reject H0

as z test statistic is beyond [-1.96, 1.96] which is permissible for significance level 0.05 and also beyond [-2.58, 2.58] which is permissible for significance level 0.01

4. If you have Two tailed Z test of significance and
you have a Z test score of 2.1, and the critical region for an
alpha level of .05 is 1.96, do you ___
a. fail to reject the Ho
b. reject the Ho
c. determine there is insufficient evidence to support at
decision
d. consult a statistician to make a decision on a type XV error

1. You have a two-tailed test. The t critical value is 2.36 and
the test statistic is 3.11. Assume the null hypothesis is true. The
result is (a) Type I error (b) Type II error (c) Correct
decision
2. You have a right-tailed test. The t critical value is 1.74
and the test statistic is 1.46. Assume the null hypothesis is true.
The result is (a)Type I error (b) Type II error (c) Correct
decision
3. You have a right-tailed...

The value obtained for the test statistic, z, in a one mean
z-test is given. Whether the test is two-tailed, left tailed, right
tailed is also specified. For parts (a) and (b), determine:
a) the test statistic in a two tailed test is z= -0.88.
The p-value is : _?
At the 1% significance level, the data _____ sufficient evidence
to reject the null hypothesis in favor of the alternative
hypothesis because the obtained p-value is _______ the significance
level....

A researcher conducted a single-sample null hypothesis test with
the z-statistic. The researcher reports that z = +1.30. This
z-statistic was calculated from sample data that was drawn from a
normal population. The researcher sets α = .05 and uses a
two-tailed test. On the basis of his data, the researcher decides
to fail to reject the null hypothesis. Did the researcher make the
correct decision or did he make an error? If he made an error, what
type of...

Situation 1: Ni = 30, α = .05
(two-tailed test)
Situation 2: Ni = 30, α = .01
(two-tailed test)
a.) Find the critical values for each of the
situations.
b.) In which situation is there less of a chance of
making a Type I error? Why?
c.) What is the effect of changing alpha from .05 to.01
on the probability of making a Type II error?

The value obtained for the test statistic, z, in a one-mean
z-test is given. Whether the test is two-tailed, left tailed, or
right-tailed is also specified. For parts (a) and (b), determine
the P-value and decide whether, at the 11% significance level,
the data provide sufficient evidence to reject the null hypothesis
in favor of the alternative hypothesis.
a) The test statistic in a left-tailed test is z=-1.65
the P-value is ___ (round to three decimal places as
needed.)
At...

a. For the following degrees of freedom, list the critical
values for a one-tailed and two-tailed test at a .01 and .05 level
of significance.
.01 .05
df = (Infinity) ___ ___ (One-tailed test)
df = (Infinity) ___ ___ (Two-tailed test)
b. Refer to Table 8.4 in Chapter 8. How do the critical values
you listed in the previous question compare with those listed for
the z-distribution. Explain.

Find the P-value for the hypothesis test with the standardized
test statistic z = 0.52, Right-tailed test, and level of
significance = 0.05. Decide whether to reject H0 or fail to reject
H0.

You calculate a one-tailed z-test and find that for your study,
z = 1.40, p > .05.
A. What is the proportion of the curve that is in the critical
region?
B. Is this a Type I or Type II error?
C. Do you reject or fail to reject the null hypothesis?
D. What is the confidence interval?
For a normal distribution with a population mean μ of 80 and a
population standard deviation (σ) of 50, find each probability...

A researcher did a one-tailed hypothesis test using an alpha
level of .01, H0 was rejected.A colleague analyzed the same data
but used a two-tailed test with α=.05, H0 was failed to reject. Can
both analyses be correct? Explain your answer.
