Question

Provide the null hypothesis and the
statistical test that would be used for the following research
hypothesis: *Whites in suburban areas who are convicted of more
than 3 offenses receive longer prison sentences than whites in
suburban areas that are convicted of 3 offenses or less*.

Answer #1

Since the two population are different we use the t test for two independent samples . The claim is to check that the prison sentences for sub urban whites who convicted less than 3 crimes is fewer than those who convicted more than 3 offences

Null Hypothesis , H_{0}: (The
mean of the two groups are same )

Alternative Hypothesis,H_{a}:

The test statistic is

If the calculated value is greater than the critical value , we reject the null hypothesis and conclude that kur claim is true at the given level of significance

3. Provide the null
hypothesis and the statistical test that would be used for the
following research hypothesis: Whites in suburban areas who are
convicted of more than 3 offenses receive longer prison sentences
than whites in suburban areas that are convicted of 3 offenses or
less.

1. Provide the null hypothesis and the statistical test that
would be used for the following research hypothesis: Whites in
suburban areas who are convicted of more than 3 offenses receive
longer prison sentences than whites in suburban areas that are
convicted of 3 offenses or less.
2. A colleague of yours is struggling to make a decision on
sample size. What advice would you provide to your colleague in
terms of larger or smaller sample sizes? Why?
Please answer...

The prison administration initiated a project to identify
certain statistical relationships. They collected data on a sample
of prisoners at a federal prison. They wanted to present
information about the relationship between an prisoner's race and
the offense for which they were convicted.
1) Identify the level of measurement for each variable.
2) What inference test (hypothesis test) would be used to carry
out this research analysis?
State the Null and Alternative Hypotheses for the research

For the following research question, state an appropriate null
and alternate hypothesis and determine whether the hypothesis test
would be directional or non-directional and whether it would be a
test of difference, equivalence, superiority, or non-inferiority.
Do students who get at least 8 hours of sleep the night before an
exam get different exam grades than those who get less than 8 hours
of sleep

In which case would testing the null hypothesis involve a
two-tailed statistical test?

Suppose a random sample of 150 universities is used to test the
null hypothesis that the average number of spam emails economics
graduate students receive in a month is
46.92.The value of the test statistic is found to be 1.02
1. If the null is tested against the alternative hypothesis that
the number of spam emails is not 46.92, the smallest significance
level at which you can reject the null hypothesis is.
2. If the null is tested against the...

The ______________ hypothesis determines the region of the
sampling distribution that is used in the hypothesis test. If this
hypothesis states that the mean is less than a value, then we
should use a _________-tailed test. If this hypothesis states that
the mean is greater than a value, then we should use a
__________-tailed test. If this hypothesis states that the mean is
not equal to a value, then we should use a __________-tailed test.
In a statistical test, if...

Provide the a) Null hypothesis b) Alternative hypothesis, c)
dependent variable d) independent variable, e) what statistical
test would be best to use to conduct the study for the Research
Question below;
Is there a relationship between drop-out rate of high school
students placed into exceptional student education category of
learning disabled and students not placed into exceptional student
education category of learning disabled?

An experiment was designed to test a hypothesis that stated that
high-drive subjects would be able to learn a simple task much more
quickly than would low-drive subjects. The experimenter’s
operational definition of drive was each subject’s score
on the Manifest Drive Scale. Twenty people who scored high on the
scale (high-drive) and 20 people who scored low on the scale
(low-drive) were given a simple task to learn.
-Is the independent variable a true independent variable? (true
or false)...

a.
State the null hypothesis.
b.
Identify the appropriate statistical test
c.
Calculate the appropriate test statistic. Make sure to report the
degrees of freedom for the statistical test (if appropriate). You
must show your work to receive full credit.
d.
State your conclusions (use a two-tailed test with a = .05 for all
tests).
e.
Compute an effect size.
A researcher knows that the weights of 6 year olds are normally
distributed with m = 20 kg and s...
