Let's find the total score of all 25 students: Total score = Average score x Number of students Total score = 70 x 25 Total score = 1750 We can find the minimum possible total score by assuming that all students scored 40. In that case, the total score would be: Minimum total score = 40 x 25 = 1000 Therefore, the range of the scores is: Maximum possible total score - Minimum possible total score Range = 1750 - 1000 Range = 750
