Question:
The effect of store layout on sales is of strong interest to retailers. In an experiment involving the layout of nonfood sections of supermarkets in the United Kingdom, researchers compared the impact of switching to alternative layouts— including the boutique layout and the free flow layout— for a number of similar sized, randomly selected supermarkets that had been using the standard grid (parallel aisles) layout (source: The Location and Merchandising of non food in Supermarkets, C. Hart, M. Davies, utdt.edu). Assume that the data below shows the change in sales per square foot (converted to US$) for six stores that switched to the boutique layout in their nonfood sections and six stores that switched to the free flow layout.
a. Compute the sample means and sample standard deviations (s1 and s2) here.
b. Compute the pooled estimate of population standard deviation.
