You can use hypothesis testing to test a claim made by another statistician. Find an article in a newspaper, magazine or on the internet which makes a claim about one population mean or one population proportion. The claim may be based upon a survey that the article was reporting on. You will conduct a survey to verify or dispute the results of the hypothesis test.
Describe your sampling method in detail and why you chose that method. You may use cluster, stratified, systematic, or simple random sample using a random number generator, but do not use convenience sampling. If you have another method you would like considered, please contact your instructor for approval.
Create your survey.
Conduct a mock survey to collect your data. Your sample must be at least 50. Submit the data with your assignment.
State the appropriate statistics that are a result of your data collection. Include sample size, sample mean and sample standard deviation OR sample size and the number successes.
Record the hypothesis test based on your experiment. Make your decision using a 5% level of significance. Include the 95% confidence interval. Include the test statistic, critical value, and P-value. Clearly communicate your decision.
Create a visual that illustrates your data. Use your creativity! This could be a bar graph, pie chart, histogram or boxplot depending on the nature of your survey and data. Create a visual that makes sense for your data and gives the reader useful information about your data.
Written report that describes your project. The summary must include:
Brief article review, including the source
Statement of the claim made in the article
Detailed description of how, where and when you collected your data, including your sampling technique
Conclusion about the article claim considering your hypothesis test.
Include a discussion about P-value and alpha or the test statistic and critical value. How did you make your decision?
Include a conclusion statement in using words, in the context of the claim, as if you were writing for the general public and not a group of statisticians.
Provide an interpretation of the confidence interval in the context of the claim.
Reference and discuss the visual you created at an appropriate part of your report.
Data Collected and Reported. Include your raw data from the survey, the appropriate statistics that are a result of your data, and the test statistic, critical value and P-value. Refer to the Data Analysis section.
