Question

Suppose that you have set a cutoff value of 0.2 and calculate a p-value of 0.11, should you reject the null hypothesis?

Yes or No?

Answer #1

Test the hypothesis using the P-value approach. Be sure to
verify the requirements of the test.
H0: p=0.2 versus H1: p>0.2
n=200; x=55, α=0.1
Is np0(1−p)0≥10?
Yes
No
Use technology to find the P-value.
P-value=__?__
(Round to three decimal places as needed.)
▼
Do not reject
Reject
the null hypothesis, because the P-value is
▼
greater
less
than α.

Suppose you have a two sided hypothesis test, Ha:
? ? ?0 with a test statistic
z=2.70. Determine the p-value and give the decision of
this test. Use a 5% level of significance.
a) P-value of 0.0035, reject the null hypothesis.
b) P-value of 0.0035, fail to reject the null hypothesis.
c) P-value of 0.9931, fail to reject the null hypothesis.
d) P-value of 0.0069, reject the null hypothesis.

Suppose that the
p-value associated with a test statistic is 0.15. In this case,
Group of answer choices
should reject the null at the 10-percent and 5-percent levels of
significance, but not at the 1-percent level.
should reject at the 5-percent level of significance, but not at
the 5-percent level or lower levels of significance.
you should reject the null hypothesis at the 10-percent,
5-percent, and 1-percent levels of significance.
should not reject the null hypothesis at the 10-percent,
5-percent,...

Given the hypothesis that ?0:?=0.2 against ?1:?>0.2 (?????)
and the test statistics,
?=1.58.
1. Find the p-value.
A. 0.9429
B. 1.886
C. 0.0571
D. 0.1142
E. 0.5793
2. Assuming that the significance level is 0.05, what is
the conclusion?
A. Reject the null hypothesis. There is sufficient evidence to
support the claim that ?>0.2.
B. Reject the null hypothesis. There is sufficient evidence to
warrant rejection the claim that ?>0.2.
C. Fail to reject the null hypothesis. There is not...

6. If you have a P value of .59 and α is set at .05 do
you
a. Reject Ho
b. Fail to reject Ho
c. Accept Ho
d. Make a type II Error

Given the following information calculate the z test statistic,
p-value and state whether or not to reject the null hypothesis
based on the significance level.
Hoμ=15,Haμ≠15
x¯=12.1,σ=1.5,n=16,α=0.10
What is z
What is p-value
Reject the null or fail to reject the null?

You are testing Ho: p=20% at 5% significance level. You have
collected the data and the p-value was 6%. As a good student of QM,
you report declares that there is no statistical justification to
reject the null hypothesis. Your client says that such a
declaration has no meaning - either accept or reject the null
hypothesis. if the null hypothesis is accepted there is a chance
that you may be making an error.
explain why you cannot compute the...

In each part, we have given the significance level and the
P-value for a hypothesis test. For each case determine if the null
hypothesis should be rejected. Write "reject" or "do not reject"
(without quotations).
(a) α=0.01,P=0.06α
answer:
(b) α=0.07,P=0.06α
answer:
(c) α=0.06,P=0.06

1.Suppose you wish to test the null hypothesis that the mean of
a population is 100 versus the alternative that the mean is not
equal to 100. You then take a sample and calculate a sample of mean
of 90. Which of the following conclusions is correct?
a.
You should reject the null hypothesis
b.
You should not reject the null hypothesis
c.
You should reject the null if n > 30, otherwise do not
reject
d.You should accept the...

Questions D-F
d) You conduct a hypothesis test for the
population proportion. After you calculate the z test statistic,
you find that your p-value = 0.059. Using alpha (α) = 0.05 level of
significance, what is your decision regarding the null hypothesis?
Choose from the following.
- Reject the null hypothesis and reject the alternative
hypothesis
- Accept the null hypothesis
- Do not reject the null hypothesis
- Reject the null hypothesis and accept the alternative
hypothesis
e) You...
