Corrected question;
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. There are 1143 middle school students in the Timpony School District. Based on the data, what is the most reasonable estimate for the number of Timpony School District middle school students who average watching more than 4 hours of TV each day?
Step-by-step explanation:
Given;
Number of sample students = 60
Number of Sample students with more than 4 hr TV= 14
Total population = 1143
Estimate number of students with more than 4hr of TV per day is n;
n = 14/60 × 1143 = 266.7
n ~= 267
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.
