Option 2 Scenario

Option 2 Data Set

1. Discuss the process for hypothesis testing.
   1. Explain the 8 steps of hypothesis testing
   2. 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.

   If you selected Option 1 (Salaries):

   Claim: The average salary for alljobs in Minnesota is less than $65,000. Test the claim using α = 0.05and assume your data is normally distributed and σ is unknown.

   If you selected Option 2 (Patients at NLEX hospital):

   Claim: The average age of allpatients admitted to the hospital with infectious diseases is less than65 years of age. Test the claim using α = 0.05 and assume your datais normally distributed and σ is unknown.

   Based on your selected topic, perform and document the following steps:

   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? Show your calculation
   5. What is the P-value? Explain how you determined it
   6. What is the critical value? Explain how you calculated it
   7. What is your decision? Reject the null or do notreject the null? Explain why you made your decision including theresults for your p-value and the critical value.
   8. State the final conclusion in non-technical terms.

Please show your work for the construction of the test-statisticand explain your process for finding the p-value and critical value.You may use the Equation Editor to format your calculation steps on theWord document or attach an Excel spreadsheet clearly showing eachcalculation for #B4 and #B5, but your answers still need to appear onthe Word document. Also, be sure to number each response in your paper using the same numbers as above
