In this problem we revisit the data from Bravman Clothing in Problem 22. The file bravman which contains 25 observations consisting of the wait time the customer experienced during the order process, the customer’s purchase amount, the customer’s age, and the customer’s credit score.

a. Create a scatter-chart matrix for these data. Include the variables wait time, purchase amount, customer age, and credit score. (Note: Excel does not contain an automatic tool to generate a scatter chart matrix. This problem can be solved by either using a different software package or by creating the scatter charts individually in Excel.)

b. What can you infer about the relationships between each pair of variables based on the scatter chart matrix?

Problem 22

Bravman Clothing sells high-end clothing products and is launching a service in which they use a same-day courier service to deliver purchases that customers have made by working with one of their personal stylists on the phone.

In a pilot study, Bravman collected 25 observations consisting of the wait time the customer experienced during the order process, the customer’s purchase amount, the customer’s age, and the customer’s credit score. The file bravman contains the data for these 25 observations.
