An online shopping retailer is experimenting with two different versions of its website. The webpage randomly loads one of the two versions to every new request for the webpage. Version A was viewed by 3,250 customers from whom 1,320 ending up buying a product of the website. Version B was viewed by 2,870 customers from whom 1,250 purchased a product. The retailer is asking you whether any of the two version is associated with higher sales conversion (i.e., higher chance of a customer purchasing). What would you answer to them?
