Answer:
so Median Still remain the same = 55 kg
Step-by-step explanation:
The median weight of a group of 79 students
is found to be 55 kg
=> 39 students Have Weight ≤ 55 kg
& 39 Students have Weight ≥ 55 kg
and one students Have 55 kg
6 More students added
=> 85 Students
42 Students each side of Median
50,51,52,59.5,60,61kg are weight of 6 new students
50,51,52 < 55
=> 39 + 3 = 42 Have Weight ≤ 55 kg
59.5,60,61 > 55
=> => 39 + 3 = 42 Have Weight ≥ 55 kg
& one student in middle weigh 55 kg
so Median Still remain the same = 55 kg
