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
