7. A research is conducted to determine if listening to piano instrumental music would enhance vocabulary recall. The researcher exposed a group into two conditions (with music and no music) and recall as the dependent variable was measured using non-sense syllables. The scores are given below (a higher score means higher recall).: Participant No music With piano instrumental music A B C D E F G H I J K L M N O P Q R S T 38 99 578 7 8 5 526382 5 4 1 2 6 6 6 7 9 6 6 7 8 10 8 8 5 8 9 7 5 7 7 8 сл 7.1. Determine if there is a significant difference between the paired observations at a = .05. 7.2. Let us convert the scores into Pass or Fail (dichotomous data) so that those who scored 6 and above passed (coded as "1") and those who scored 5 and below failed (coded as
