Answer
a) Arranging the data in ascending order, we find that the middle value is 45, so the median = 45 points
b) $Q_{1}$ is 25% of the data, which is 11th value; thus $Q_{1}$ = 37 points
$Q_{3}$ is 75% of the data, which is 33rd value; thus $Q_{3} $= 55 points
c) In the Super Bowl, teams score about 45 points on average, and half of the scores are between 37 and 55 points. In a quarter of the games, the score is less than 37 points, and the maximum total is 75.
