(2) A firm is trying to decide which website to use from a set of websites. The web developer provided six designs in total. There were two factors involved in the design. The first one was with whether there was social media integration in the design or not. The second one was how many sections the website had (4, 5 or 6). Given below is the data on the time that users spent (in seconds) on each of the different designs.
