We redesigned the credit card application page in our app and randomly assigned 20,000 visitors to each version. The old page has a 10.0% completion rate and the new page has 10.6%. The PM asks whether this is a significant lift and whether we can launch. Walk me through the math and tell me how you'd answer.

我们改版了App里的信用卡申请页面，新旧两个版本各随机分了2万个访客。老页面完成申请率10.0%，新页面10.6%。产品经理问这算不算显著提升、能不能上线，你现场算一下，然后怎么回答？
