Boosting sales of mobile electronics items is a key goal in a new strategic plan issued by the senior management at the general merchandiser Arlingtons. Having helped to conduct an experiment that provided evidence that sales of a mobile streaming media player are higher in a special front location than in the middle of the electronics aisle, you wonder if moving all mobile electronics items to another Co in-store location might also have effects on sales. 9 10 The strategic plan also encourages managers to make better use of kiosks, the special end-of aisle 11 endcap area that face customers as they enter aisles and suggests managers create expert counters, 12 positions that customers can visit to ask specially-trained staff questions about items for sale in a 13 particular department, such as mobile electronics, or to see live demonstrations of particular items. 14 Might these two in-store locations be combined with the two locations of the previous experiment (rhe 15 special front location and the regular in-aisle location) into one larger experiment? 16 17 You suggest an experiment in which mobile electronics in selected Arlington stores will be sold at one 18 of four in-store locations: the current in-aisle location, the special front of the store location, in a special 19 endcap kiosk, or at the expert counter position for mobile electronics. You propose to select 20 20 Arlingtons stores that have similar annual sales and divide the stores into four groups of 5 each. To each 21 group, you assign a different in-store location for mobile electronics: current in-aisle, special front, kiosk, 22 or expert counter. 23 24 Use an ANOVA hypothesis test (with alpha = 0.05) to determine if the four locations have equal mean 25 sales or if some of them are different. 26 27 In-Aisle Front Kiosk Expert 28 30.06 32.22 30.78 30.33 29 29.96 31.47 30.91 30.29 30 30.19 32.13 30.79 30.25 31 29.96 31.86 30.95 30.25 32 27.74 32.29 31.13 30.25 33 34 35
