Quantitative Analysis & Decision Making

Parameter Estimation, Inferences, and Tests of Difference

You are a marketing analyst in a large grocery store chain. Your job entails developing a robust customer knowledge base utilizing the company’s vast database of in-store purchases. To date, you have been able to build a profile of your customer base, draw inferences about different customer groupings, and compare customer behaviors across the different sales regions. Your task is to:

• Describe the business benefits of parameter estimation. Provide examples of the type of parameters that might be of interest to decision makers in areas such as marketing.
• Elaborate on how being able to estimate those parameters would benefit the quality of the resultant decisions.

• Discuss the relationship between tests of difference and hypothesis testing in the context of designing marketing promotions.
