What is a null hypothesis?
Wat is an alternative hypothesis?
Then articulate a null hypothesis and alternative hypothesis for
a research study that pertains to you're area of
specialization.
What conclusions can be drawn from this study with a
"statistically significant" result?
here is my Null Hypothesis and Alternative Hypothesis:
Null Hypothesis: There is no significant difference in the
housing expenses between married and unmarried households.
Alternative Hypothesis: There is a significant difference in the
housing expenses between married and unmarried households.
what are the type I and type II errors?
Explain the concept of survivorship. What is Type I, Type II,
and Type III survivorship? Give an example of each type and explain
how survivorship relates to population change.
Give 3 types of population dispersion with an example of
each.
Name and explain two factors that affect population growth
rates.
if possible i would appreciate an answer in a text form not
handwritten. thank you
For the following scenarios write an appropriate null
and alternative hypothesis and identify what type of test statistic
will be used. (Steps 1 & 3 of the six step hypothesis
test.)
a. A nationwide sample of influential
Republicans and Democrats was asked as part of a comprehensive
survey whether they favored lowering environmental standards so
that high-sulfur coal could be burned in coal-fired plants. The
results were:
Republicans
Democrats
No. Sampled
1100
1400
No. in Favor
115
158

in hypothesis testing if the null hypothesis is rejected
-the alternative hypothesis is likely to be true
- no conclusions can be drawn from the test
-the data must have been accumulated incorrectly
-the sample size has been to small
Explain in detail the difference between the null hypothesis and
alternative Hypothesis.
In what cases you reject the Null and apply the alternative give
a practical example.
The null hypothesis plays an important role in significance
testing. Explain the concept underlying the null hypothesis and the
role it plays in tests of statistical significance (hint: think of
the logic involved in the decision making process).
What is a null hypothesis and what is an alternative
hypothesis? How do you choose the null hypothesis in
general? Give an example What is type I error? What is type II
error? What is the significance level? What is the power of the
test? What is the p-value of a hypothesis test?.
Please type the answer. I have difficulties
understanding handwritten answers. Thanks
