Pleаse nоte thаt this questiоn cоnsists of six pаrts. You may use MINITAB to find a final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question. A company wants to test if the average number of tasks completed per day by employees is different from 20. Management randomly selects 12 employees and records the number of tasks completed in a day. For this sample the mean is 21.67 tasks and standard deviation is 2.69 tasks. Set up appropriate null and alternative hypotheses for testing the question posed by the company. Are the conditions to carry out the above stated test are satisfied? If the conditions are satisfied, explain how they were satisfied for this problem rather than simply giving a "yes" or "no" answer. Calculate the test statistic. Show your calculations. Find the rejection region for the test defined in part 1. Use 5% significance level. It is not sufficient to provide just the critical value. Clearly state the rejection region. Write the final conclusion in the context of the problem. Based on the decision you made in part 5, which error: type I or type II is possible? Explain.
