Required Information Lab Note: The tools presented in this lab periodically change. Updated Instructions, if applicable, can be found in the eBook and lab walkthrough videos in Connect Case Summary: After running diagnostic analysis on Dillard's transactions, you have found that there is a statistically significant difference between the amount of money customers spend in online transactions versus in-person transactions. You decide to take this a step further and design a predictive model to help determine how much a customer will spend based on the transaction type (online or in-person). You will run a simple regression to create a predictive model using one explanatory variable in Part 1, and in Part 2 you will extend your analysis to add in an additional explanatory variable-tender type (the method of payment the customer chooses). Data: Dillard's sales data are available only on the University of Arkansas Remote Desktop (waltonlab.uark.edu). See your Instructor for login credentials. OQ1.
