RJ's teacher gave a pop quiz in math class yesterday. The scores on the quizzes ranged from 60% to 100%. What grade did most students earn on the pop quiz?

Grade's of most student = 80% (Approx.)

Step-by-step explanation:

Given range:

Range of quiz = 60% to 100%

Find;

Grade's of most student

Computation:

⇒ Grade's of most student = Average grade

⇒ Average mean = Sum of observation / number of observation

⇒ Grade's of most student = [60 + 100] / 2

⇒ Grade's of most student = 160 / 2

Grade's of most student = 80% (Approx.)
