FAN AND MEDAL The following 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:
Weekly Duration of Outdoor Games Time (in hours) 0–2 3–5 6–8 9–11 Number of Students 30 62 8 0 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? 744 840 960 1,104

@Deadpool117
'At least 3 hours' would be all the students who play for 3 hours or more. So, you would include the students in the 3-5 column and the 6-8 column. That adds to 70, which out of 100 is 70%. You can multiply 0.70 by the number of students in the school to find the answer :)
