Summary

The Control Package Test compares marketing campaigns to see if there is a significant difference in effectiveness for different packages or offers. In this example, the positive response of 6.2% for the test package was significantly higher than the positive response rate of 3.8% for the control package. This suggests that you should use the new package design instead of the old one, but there may be other factors that you need to consider, such as any additional costs associated with the new package design.
