Answer:

267 students.

Explanation:

Let x be the total number of students who average watching more than 4 hours of TV each day.

We have been given that Timpony School District surveyed a random sample of 60 middle school students about the amount of time they watch TV. Of the students surveyed, 14 average watching more than 4 hours of TV each day.

So the probability of a student watching more than 4 hours of TV each day will be
(14)/(60)

To find the estimated number of students, who watch the TV more than 4 hours each day, we will use relative probability as it is the ratio of the occurrence of a singular event and the total number of outcomes.

So we can set a proportion as:


(14)/(60)=(x)/(1143)

Upon dividing both sides of our equation by 1143 we will get,


(14)/(60)*1143=(x)/(1143)*1143


0.23333*1143=x


266.69999=x


x=266.69999\approx 267

Therefore, approximately 267 students of Timpony School District middle school average watching more than 4 hours of TV each day.
