7/19/2016 Assessment 3 – MBA­FP6018 ­ Spring 2016 ­ Section 01 https://courserooma.capella.edu/webapps/blackboard/content/listContent.jsp?course_id=_34646_1&content_id=_3445804_1&mode=reset 1/4 ASSESSMENT 3 Hypothesis Testing 1 Overview Solve four equations based on a scenario related to hypothesis testing. Demonstrate your method, report your findings, and write a brief paragraph that details your recommendations for action. Note: The assessments in this course build upon each other, so you are strongly encouraged to complete them in sequence. Managers can use sampling techniques to make managerial decisions and draw conclusions. The statistical technique that we will use to evaluate the samples is hypothesis testing; mathematically speaking, we will use statistical techniques to evaluate the likelihood of an assertion. By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria: Competency 1: Evaluate the quality and fit of data for use in business analysis. Determine the null hypothesis and alternative hypothesis for making decisions regarding household income. Competency 3: Analyze business decision opportunities using basic inferential statistics. Compute the appropriate statistical test to determine acceptance or rejection of a null hypothesis. Compute the p­value to indicate acceptance or rejection of a null hypothesis regarding average household income. Competency 5: Apply data analysis to general business management planning and decision making. Compile findings into a management report with details for recommended actions. Competency 6: Communicate in a manner that is professional and consistent with expectations for members of the business professions.

Context Managers use hypothesis testing and statistical techniques to evaluate the likelihood of an assertion. Hypothesis testing is at the core of inferential statistics. It is the foundation of the inferential statistics used to help managers make better decisions. A typical managerial decision using hypothesis testing would be to compare samples of purchased products to ensure they conform to firm quality standards. In fact, sampling itself is a particularly useful data analysis technique. Malls and stores often sample prospective customers. So do retail fast food franchises—take a look at the bottom of your receipts the next time you purchase something. Details Attempt 1 Available Attempt 2 Attempt 3

Why is it important that a sample be random? For its validity, all hypothesis testing depends heavily on the assumption that the sample that is used was drawn using probability sampling techniques. Why is this important? What can you do if you cannot use a probability sampling technique? (For example, suppose there is no good sampling frame available for the population of interest.)
