Based on the sample proportion, 56% of the middle school students play outdoor games for at least three hours every week (56 out of 100 students).
To calculate the expected number of students in the school that would play outdoor games for at least three hours every week, we can use the proportion:
56% of 1,200 students = 0.56 * 1,200 = 672 students
Therefore, based on the sample proportion, we would expect approximately 672 students in the school to play outdoor games for at least three hours every week.
The table shows the data collected from a random sample of 100 middle school students on the number of hours they play outdoor games every week. There are 1,200 students in the school. Based on the sample proportion, how many students in the school would be expected to play outdoor games for at least three hours every week?
