Grocery Website Download Page AB Testing

In this use case I am working as an analyst for a large grossery chain. One of the goals our company has, it's to drive more customers to download thier mobile app and register for the loyalty program.

One of the goals of the company discussed here is to get more users to download the mobile app and sign up for the customer loyalty program.
