Question 1 1. Describe the 8 steps in the process for hypothesis testing. Explain the decision criteria for rejecting the null hypothesis for both the p-value method and the critical value method. Question 2 Calculations/Values Formulas/Answers Mean (x-bar) Standard Deviation n mu Test Statistic Critical Value P-value 2a. Write the null and alternative hypotheses symbolically and identify which hypothesis is the claim. Then identify if the test is left-tailed, right-tailed, or two-tailed and explain why. 2b. Identify and explain which test statistic you will use for your hypothesis test: z or t? Find the value of the test statistic. Provide your calculations in the cells designated to the right. Explain your answers below. 2c. What is the critical value? Describe the rejection region of this hypothesis test. Provide your calculations in the cells designated to the right. Explain your answers below. 2d. Using the critical value approach, should you reject the null hypothesis or not reject the null hypothesis? Explain. After making your decision, restate it in non-technical terms and make a conclusion about the original claim. 2e. Calculate the p-value for this hypothesis test, and state the hypothesis conclusion based on the p-value. Does this match your results from the critical value method? Provide your calculations in the cells designated to the right. Explain your answers below. Question 3 Calculations/Values Formulas/Answers Mean (x-bar) Standard Deviation n mu Test Statistic Critical Value P-value 3a.
