This week you will begin working on Phase 3 of your course project. Using  the same data set and variables for your selected topic that you used for  phases 1 and 2, add the following information to your analysis:Discuss the process for hypothesis testing. Explain the 8 steps of hypothesis testingWhen performing the 8 steps for hypothesis  testing, which method do you prefer; P-Value method or Critical Value method?  Why?
Perform the hypothesis test.

If you selected Option 1 (Salaries):

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 (Patients at NLEX  hospital):

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  Î± = 0.05 and assume your data is normally distributed and σ is unknown.

Explain.Which test statistic will you use for your         hypothesis test; z-test or t-test? Explain.What is the value of the test-statistic? Show         your calculationWhat is the P-value? Explain how you determined         it What is the critical value? Explain how you         calculated itWhat is your decision? Reject the null or do         not reject the null? Explain why you made your decision including the         results for your p-value and the critical value.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. You may use the Equation Editor to format your calculation steps on the  Word document or attach an Excel spreadsheet clearly showing each calculation  for #B4 and #B5, but your answers still need to appear on the Word document. Also, be sure to number each response in  your paper using the same numbers as above
