Please provide explanation step by step Thank you!

Marketing professors at Robert Morris and Kent Sate universities examined children's recall and recognition of television advertisements. Two groups of children were shown a 60-second commercial for Sunkist Fun Fruit Rock-n-Roll Shapes. One group (the A/v group) was shown the ad with both audio and video; the second group (the video-only group) was shown only the video portion of the commercial. Following the viewing, the children were asked to recall 10 specific items from the ad. The number of the 10 items recorded correctly by each child is summarized in the table. The researchers theorized that "children who receive an audiovisual presentation will have the same level of mean recall of ad information as those who receive only the visual aspects of the ad". Video Only Group A/V Group n1 = 15 n₂ = 15 T₁ = 3.70 T2 = 3.30 $1 1.98 S2 = 2.13 =
