Josephine Mater works for the supply chain analytics division of Trader Joe's, a national chain

of specialty grocery stores. Trader Joe's is considering a redesign of its supply chain. Josephine

knows that Trader Joe's uses frequent truck shipments from its distribution centers to its retail

stores. To keep costs low, retail stores are typically located near a distribution center. The file

traderjoe.csv contains data on the location of Trader Joe's retail stores. Josephine would like to

use k$-$means clustering to help guide a proposal for positioning distribution centers.
