statistics phase3

This week you will begin working on Phase 3 of your course project. Using the same data set and variables for your selected topic, add the following information to your analysis:

  1. Discuss the process for hypothesis testing. 
  • Discuss the 8 steps of hypothesis testing? 
  • When performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why?
  1. Perform the hypothesis test.
  • If you selected Option 1:
    • Original Claim: The average salary for all jobs in Minnesota is less than $65,000. 
    • Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.
  • If you selected Option 2:
    • Original Claim: The average age of all patients admitted to the hospital with infectious diseases is less than 65 years of age.
    • Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.
  • Based on your selected topic, answer the following:
  1. Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.
  2. Is the test two-tailed, left-tailed, or right-tailed? Explain.
  3. Which test statistic will you use for your hypothesis test; z-test or t-test? Explain.
  4. What is the value of the test-statistic? What is the P-value?
  5. What is the critical value?
  6. What is your decision; reject the null or do not reject the null? 
    1. Explain why you made your decision including the results for your p-value and the critical value.
  7. State the final conclusion in non-technical terms.

Please show your work for the construction of the test-statistic and explain your process for finding the p-value and critical value. Be sure to use the Equation Editor to format your equations.
