Answer:
267 middle school students
Step-by-step explanation:
Sample surveyed consists of 60 students.
Of the students surveyed, 14 average watching more than 4 hours of TV each day. That represents 14/60 = 0.23 of the total.
There are 1143 middle school students
Then, a reasonable estimate for the number middle school students who average watching more than 4 hours of TV each day is 0.23*1143 ≈ 267
