Retail chain Kroger has more than 2700 locations and is the largest supermarket in the United States based on revenue. Kroger has invested heavily in data, technology, and analytics. Feeding predictive models with data from an infrared sensor system called QueVision to anticipate when shoppers will reach the checkout counters, Kroger is able to alert workers to open more checkout lines as needed. This has allowed Kroger to lower its average checkout time from four minutes to less than 30 seconds (Retail Touchpoints). Consider the data in the file Checkout. The file contains 32 observations. Each observation gives the arrival time (measured in minutes before 6 p.m.) and the shopping time (measured in minutes). DATA file a. Select the correct scatter diagram for arrival time as the independent variable. A. 60 50 40 30 20 10 Shopping Time (Minutes) 20 40 60 8- 80 Arrival Time (Minutes before 6 p.m.) 100 120 140 160
