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 testing
 When performing the 8 steps for hypothesis testing, which method do you prefer; PValue method or Critical Value method? Why?
 Discuss the process for hypothesis testing.
 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 α = 0.05 and assume your data is normally distributed and σ is unknown.
Based on your selected topic, perform and document the following steps: Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.
 Is the test twotailed, lefttailed, or righttailed? Explain.
 Which test statistic will you use for your hypothesis test; ztest or ttest? Explain.
 What is the value of the teststatistic? Show your calculation
 What is the Pvalue? Explain how you determined it
 What is the critical value? Explain how you calculated it
 What is your decision? Reject the null or do not reject the null? Explain why you made your decision including the results for your pvalue and the critical value.
 State the final conclusion in nontechnical terms.
Please show your work for the construction of the teststatistic and explain your process for finding the pvalue 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.
