12 students scored in the range 65 to 70
13 students scored in the range 65 to 80

wouldn't that mean only 1 student scored in the range 71 to 80 ?

Why would you read "13 students have grades in the range of 65 to 80" and conclude that "13 students have grades in the range 71 to 80"? 65 is NOT 71!

13 students have grades in the range 65 to 80 but 12 of those have grades in range 65 to 70.
