  1. Purpose:What was the purpose of your analysis, and what is your approach?
  2. Define a random sample and two hypotheses (means) to analyze.
  3. Sample:Define your sample. Take a random sample of 100 observations for your region.
  4. Describe what is included in your sample (i.e., states, region, years or months).
  5. Questions and type of test:For your selected sample, define two hypothesis questions and the appropriate type of test hypothesis for each. Address the followingfor each hypothesis:
  6. Describe the population parameter for the variable you are analyzing.
  7. Describe your hypothesis in your own words.
  8. Describe the inference test you will use.
  9. Identify the test statistic.
  10. Level of confidence:Discuss how you will use estimation and conference intervals to help you solve the problem.

1-Tail Test

  1. Hypothesis:Define your hypothesis.
  2. Define the population parameter.
  3. Write null (Ho) and alternative (Ha) hypotheses.
  4. Specify your significance level.
  5. Data analysis:Analyze the data and confirm assumptions have not been violated to complete this hypothesis test.
  6. Summarize your sample data using appropriate graphical displays and summary statistics.
  7. Provide at least one histogram of your sample data.
  8. In a table, provide summary statistics including sample size, mean, median, and standard deviation.
  9. Summarize your sample data, describing the center, spread, and shape in comparison to the national information.
  10. Check the conditions.
  11. Determine if the normal condition has been met.
  12. Determine if there are any other conditions that you should check and whether they have been met.
  13. Hypothesis test calculations:Complete hypothesis test calculations, providing the appropriate statistics and graphs.
  14. Calculate the hypothesis statistics.
  15. Determine the appropriate test statistic (t).
  16. Calculate the probability (pvalue).
  17. Interpretation:Interpret your hypothesis test results using the p value method to reject or not reject the null hypothesis.
  18. Relate thepvalue and significance level.
  19. Make the correct decision (reject or fail to reject).
  20. Provide a conclusion in the context of your hypothesis.

  7. Provide at least one histogram of your sample data.
  8. In a table, provide summary statistics including sample size, mean, median, and standard deviation.
  9. Summarize your sample data, describing the center, spread, and shape in comparison to the national information.
  10. Check the assumptions.
  11. Determine if the normal condition has been met.
  12. Determine if there are any other conditions that should be checked on and whether they have been met.
  13. Hypothesis test calculations:Complete hypothesis test calculations, providing the appropriate statistics and graphs.
  14. Calculate the hypothesis statistics.
  15. Determine the appropriate test statistic (t).
  16. Determine the probability (pvalue).
  17. Interpretation:Interpret your hypothesis test results using thepvalue method to reject or not reject the null hypothesis.
  18. Relate thepvalue and significance level.
  19. Make the correct decision (reject or fail to reject).
  20. Provide a conclusion in the context of your hypothesis.
  21. Comparison of the test results:See Question 3 from the Scenario section.
  22. Calculate a 95% confidence interval. Show or describe your method of calculation.
  23. Interpret a 95% confidence interval.
