a. Create a bar chart, showing the average retail price by store (Store Postcode). Adjust the y-axis scaling to magnify differences. Which store has the highest average? Which has the lowest? Use the Local Data Filter (under the red triangle > Scripts) to isolate these two stores.

b. To better compare retail prices across stores, create side-by-side boxplots of retail price by store. Now compare the prices in the two stores above. Does there seem to be a difference between their price
distributions?
