A researcher is working with the owner of several supermarkets in a large city. The owner wants to know if weekly sales (total number purchased) of a particular grocery item is affected by: (a) the size of the store (small or large), (b) the shelf location of the grocery item (low or high), and (c) whether there is an interaction between size of store and shelf location on the weekly sales of the grocery item. A random sample of 24 supermarkets is selected for the study. The researcher conducts a 2 X 2 ANOVA to help in answering the owner's questions. Please enter and check data carefully. Please use an alpha of .05 for all analyses.
