Linda, the manager of a large supermarket, keeps four checkouts open. However, she has noticed queues for registers 1 and 2. She kept a record of which registers 2000 shoppers chose for checkout, and these were found to be as follows:

Register 1	Register 2	Register 3	Register 4
677	550	402	371

Based on these data, can Linda conclude that an unequal number of shoppers are likely to use each of the registers? Use a 5% level of significance.
