points$)$

The file LaptopSalesJanuary$2008.$csv contains data for all sales of laptops at a computer

chain in London in January $2008.$ This is a subset of the full dataset that includes data for

the entire year.

A$.$ Bar Chart: Create a bar chart, showing the average retail price by store. Which store

has the highest average? Which has the lowest?

B$.$ Boxplots: 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 from $($a$).$

Does there seem to be a difference between their price distributions?
