In this module you will begin working on Phase 3 of your course project. Using the same data set and variables the following 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?
  2. Perform the hypothesis test.
      • 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, the population standard deviation, is unknown.

      5. What is the critical value?
      6. What is your decision; reject the null or do not reject the null?
      7. Explain why you made your decision including the results for your p-value method or the critical value method.
      8. 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.
