  1. List all scores: Step 11: List all the scores to see what we're working with. 65,72,67,82,72,91,67,73,71,70,85,87,68,86,83,90,74,89,75,61,65,76,71,65,91,79,75,69,66,85,95,74,73,68,86,90,70,71,88,6865, 72, 67, 82, 72, 91, 67, 73, 71, 70, 85, 87, 68, 86, 83, 90, 74, 89, 75, 61, 65, 76, 71, 65, 91, 79, 75, 69, 66, 85, 95, 74, 73, 68, 86, 90, 70, 71, 88, 68
  2. Sort scores: Step 22: Sort the scores from smallest to largest to make it easier to count.\newlineSorted scores: 61,65,65,65,66,67,67,68,68,68,69,70,70,71,71,71,72,72,73,73,74,74,75,75,76,79,82,83,85,85,86,86,87,88,89,90,90,91,91,9561, 65, 65, 65, 66, 67, 67, 68, 68, 68, 69, 70, 70, 71, 71, 71, 72, 72, 73, 73, 74, 74, 75, 75, 76, 79, 82, 83, 85, 85, 86, 86, 87, 88, 89, 90, 90, 91, 91, 95
  3. Count scores between 7070 and 9090: Step 33: Count the scores that are between 7070 and 9090. Count: 7070, 7070, 7171, 7171, 7171, 7272, 7272, 7373, 7373, 909011, 909011, 909033, 909033, 909055, 909066, 909077, 909088, 909099, 909099, 707011, 707011, 707033, 707044, 707055, 9090, 9090 (Note: 9090 is included because the question says "between 7070 and 9090" which usually includes the end points in statistics)
  4. Consider excluding 9090: Step 44: Realize that including 9090 might be a mistake because "between" could mean strictly between 7070 and 9090, not including 9090.
