Question

A researcher is testing a hypothesis of a single mean. The
critical *z* value for = .05 and a one-tailed test is 1.645.
The observed *z* value from sample data is 1.13. The
decision made by the researcher based on this information is to
______ the null hypothesis.

Answer #1

**The decision made by the researcher based on this
information is to accept
(fail to reject) the null hypothesis.**

[*explanation*:-

test statistic :-

the critical value of z at alpha=0.05 is:-

the positive critical value indicates that it is a right tailed test .

decision:-

so, we * fail to reject the null
hypothesis*.]

**LIKE** if possible...

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...

The negative critical value for a two-tailed hypothesis testing
on the mean µ at the 5% level of significance for a sample of size
n = 11 (Assume σ not known) is:
t0.025,10= -2.228; B.
Z0.025 = -1.96; B.
Z0.05 =- 1.645;
t0.05,10 = - 2.10

Hypothesis Tests with Z-statistics
The mean for the SATs for all high school students was 500, with
a standard deviation of 100. 75 students from Rio Hondo were tested
and they produced a mean of 510.
a. Who are the groups being compared/tested?
b. What are the null and research hypotheses?
c. what are the numbers needed for the z statistic?
d. What is the z statistic?
e. For a two tailed test at .05 significance, the critical area is...

1. Calculate the critical degrees of freedom and
identify the critical t value for a single-sample t test in each of
the following situations, using p=.05 for all scenarios. Then,
state whether the null hypothesis would fail to be rejected or
rejected:
a. Two-tailed test, N = 14, t = 2.05, (df=
Answer:, critical t = Answer:, Reject or Fail to Reject
Ho:
Answer:
b. One-tailed test, N = 14, t = 2.05, (df=
Answer:, critical t = Answer:, Reject...

1.
if You are testing a hypothesis about a population proportion and a
sample size is over 100 what is the proper test statistic to use?
A) z statstic
B) chi-square
c) t statistic
d) not enough data
2. If you are using the critical value approach to do a single
tailed hypothesis test on the population mean, what impact will a
smaller standard error have on the critical value of your test
statistic?
A) critical value will increae
b)...

Using the traditional hypothesis testing approach, calculate the
critical value for testing the null hypothesis that the population
mean is greater than or equal to 8, given a sample
size of 32, a population standard deviation
3.63, and a significance level of
0.05.
K =
Round to two decimals.

1.- A researcher obtains t = 2.25 for a
repeated-measures study using a sample of n = 10
participants. Based on this t value, what is the correct
decision for a two-tailed test?
a.
Reject the null hypothesis with α = .05 but not with
α = .01
b.
Reject the null hypothesis with both α = .05 and
α = .01
c.
Fail to reject the null hypothesis with both α = .05
and α = .01
d.
Cannot...

Consider the non-parametric methods for
creating confidence intervals for a single mean and hypothesis
testing for a single mean. Answer each of the following questions
with one of the following options: confidence
interval estimation, hypothesis testing, both, or neither.
(1 point) Which method involves shifting the sample data?
(1 point) Which method creates a distribution that is centered
at the observed sample mean?
(1 point) Which method involves using sample data and sampling
with replacement?
(1 point) Which method requires...

a researcher conducts a hypothesis test to evaluate the effect
of the treatment. the hypothesis test produces a z-score of z=
2.75. Assuming that the researcher is using a two-tailed test,what
decision should be made?

Based on the information provided for this hypothesis testing,
what decision should you come to? (Assume that the population is
normally distributed). Note that you need to complete the 5 step
hypothesis testing. Be sure to include the cut-off sample score,
the sample score on the comparison distribution, and the conclusion
you reach.
Mean=5, SD=1, Sample Score=7, .05 level of significance,
one-tailed.
