Question
a. As the regional sales manager for ABC Foods, you are interested in comparing the sales volume of ABC cola when the soft drink is displayed in the normal shelves as compared to an end-aisle promotional display. To test the effectiveness of the end- aisle displays, you select 20 stores from the ABC supermarket chains that all experience similar storewide sales volumes. You then randomly assigned 10 of the 20 stores to group 1 and the other 10 stores to group 2. The managers of the 10 stores in group 1 place the ABC cola in the regular shelves while the 10 stores in group 2 use the end-aisle promotional display. At the end of one week, the sales of ABC cola are recorded, as follows: 22 40 34 64 Normal 52 62 84 56 Display Location 30 59 52 83 End-Aisle 71 76 66 90 54 77 67 84 Are the mean weekly sales of ABC cola the same when using a normal shelf location and when using an end-aisle display? Test at the .05 significance level. Be sure to show all of the steps. Also find the p-value.
