(a) Find the median weight.
(b) If a student of weight 42 kg joins the group. What is the median weight of the new run​

Answer 1

Answer:

i) Ans=40kg

ii0 Ans=42kg

Step-by-step explanation:

i) Arranging the data in ascending order,

22kg,25kg,29kg,32kg,35kg,45kg,46kg,56kg,58kg,63kg

The two middle terms are=35 and 45

So, Median=(35+45)/2

                  =>80/2=40

Ans=40kg

ii)If 42kg is added in the group Then the values are,

22kg,25kg,29kg,32kg,35kg,42kg,45kg,46kg,56kg,58kg,63kg

So the middle term is 42

So median=42kg
