 Americans Approve of New Gun Law but Few Say It Will Reduce Gun Violence a Lot | Pew Research Center a. The specific hypothesis that I would like to test is whether the sample proportion of U.S. adults who support the new gun law passed by Congress is significantly different from the claimed proportion of 64%. b. Null and alternative hypotheses using formal notation: H0: p = 0.64 (claim) H1: p ? 0.64 Where p represents the true proportion of U.S. adults who support the new gun law passed by Congress. The population I will be trying to infer my result to is all U.S. adults, as the sample data is representative of this population according to the article linked. My instructors feedback was This study will work, but your hypothesis needs to be revised. You've fallen into the trap of using the sample proportion as the reference value in the hypotheses. The P-value for this test will always be 1. The hypotheses should be independent of the data and moreover should be in mind before collecting/looking at the sample results. Can you come up with a question based on one of the survey questions asked without looking at the results obtained? As well as an image of the table “Americans largely supportive of new gun law, but most would like congress to do more”
 

MAT 157
Final Project
MAT 157 Inferential Statistics Final Project
Goal: Use Quantitative Inferential Statistical Methods to answer a question relevant to you. This
can be done in a variety of ways including hypothesis test on a mean, proportion, two means, or
two proportions. You can also use the methods in Chapters 10 and 11 (linear
regression/correlation, chi-square tests)
Requirements:
1. Ask your own question related to a topic of interest or find a published “claim”. Make
sure this question can be answered with accessible quantitative data sets. Experimental
or observations studies will be fine. Self-administered convenience samples are not
appropriate. Find sample data that is representative of the population you are analyzing
and provide the link (and link to claim if applicable). If any links are to a lengthy website,
article, research paper etc. then include a summary or screenshot of the specific
data/information you are using.
· Be sure you know the sample size.
· If you are doing an analysis of means, be sure you have or can calculate the
standard deviation.
· In your written submission be sure to discuss the sample data you are using.
2. Determine a specific hypothesis that you would like to test.
a. State the hypothesis in non-technical terms (ex: A majority of Polk county Iowans
approve of the U.S. President.)
b. State the null and alternative hypotheses using formal notation.
(ex: H0: p = 0.5 H1: p > 0.5 where p is the proportion of Polk county Iowans
who approve of the U.S. President)
3. Indicate the population you intend to infer your result to. [Hint: Your sample should be
representative of this population.]
4. Carry out an appropriate hypothesis test using StatCrunch. Thoroughly report your
findings by including:
a. Describe the sampling method and any other details about the data collection
process.
b. State your sample statistic(s).
c. Describe the statistical test used and the test statistic value using the appropriate
notation.
d. State the P-value.
e. State the conclusion and interpret the result in context. [Hint: This should
reference the P-value and answer your original question of interest.]
f. State an appropriate confidence interval based on the sample data.
g. Interpret this confidence interval in context, explain how it supports the results
from the hypothesis test.
h. Are the results both statistically and practically significant?
5. Submit a report with answers to 1-4. Include any links, raw data and screen shots from
analysis in StatCrunch at the end under a heading ‘Appendix’. See over for template.
MAT 157
Final Project
Title (give title appropriate to your topic)
Introduction
Write a paragraph introducing the reader to the topic and question/claim.
Sample Data
Write a paragraph or two detailing the data that will be used to answer the question/claim.
No links or screenshots here but write in your own words (see Appendix at end). Be sure
to include answers to 4 a. (describing the sampling method and any other details about
the data collection process) and 4b. (report sample statistics) here also.
Population
Write a sentence indicating the population results will be inferred to (3. in project
directions)
Hypotheses
State the specific hypothesis that will be tested here in non-technical terms as well as in
formal notation (4 a. and b. in project directions).
Analysis
Write a paragraph with the hypothesis test results stating the statistical test used,
reporting the test statistic, P-value, and conclusion in context from the test (4 c., d. and e.
in project directions). Write a second paragraph reporting an appropriate confidence
interval, interpreting this confidence interval in context and explaining how it supports
the hypothesis test result (4 f. and g. in project directions).
Conclusion
End your report by relating back to the introduction, answering the question of interest
and discussing whether results are both statistically and practically significant (4 h. in
project directions).
Appendix
Include link to source as well as screenshots of any specific information used from any
lengthly articles or websites. (Note: The reader should be able to easily verify everything
used to run the hypothesis test and construct the confidence interval). Include screenshots
of both StatCrunch hypothesis test output and StatCrunch confidence interval output.
