You compare two versions of a product flow. Version A has 200,000 users with a 10.00% conversion rate, and Version B has 200,000 users with a 10.20% conversion rate. The estimated incremental value of each additional conversion is $8, while implementing and maintaining Version B would cost $60,000 over the next year. Use a 5% significance level.
Is the observed lift statistically significant, is it business-significant, and how would you explain the difference between those two conclusions?
