Q4: Assume that TaskaBella now would like to run another A/B testing. In this A/B testing, TaskaBella would like to figure out whether they should adjust the image of their advertisement campaign. Their current image is the following. In the A/B testing, they want to know whether removing the three bags on the left of the image, as shown in the following image, will convert more people to purchase the handbag. Page 19 of 42
