(1 point) A manufacturer of bmakfast cereal is to release a new cereal called Smores. Before Smores is to be distributed in grocery stores across the country, the manufacturer conducts a study to determine if (i) the height of the shelf in which the cereal is to be displayed and (ii) the type of display will effect sales of the cereal. A statistician was hired to design an experiment to investigate if - and if so. how - does the (i) shelf-height on which the cereal is to be displayed and 0i) how Smores will be advertised in-store influence sales. She randomly picked eighteen grocery stores in a certain geographical region, each store having a similar sized customer base. Two different 'in-store' promotions were to be randomly assigned to eighteen stores. For nine stores where Promotion A was used, three stores were asked to display Smores on the lower shelf, three on the middle shelf, and three on the upper shelf. The same was done for the nine stores where in store Promotion B was used. After a period of one week, the number of boxes of Smores sold at each of the 18 stores was recorded from the item-scanning system. The data can be found in the Download .csv 'fil -.
