answer the following ​

Answer 1

Answer: Here is your answer.......please award me as a brilliantist

Step-by-step explanation:

Total number of observations(n)=10

first, we have to arrange the order of the observation in ascending or descending order

Let us arrange it in ascending order

i.e., 2.17,2.50,2.63,3.14,3.23,3.31,3.58,3.62,3.75,3.92

(a) the median weight of watermelon =(n/2+1)th observation

i.e.,  (10/2+1)th observation

     =(5+1)th observation

     =6th obervation

i.e.,   3.31 kg

(b) Mean= (sum of all observations/total number of observation)

        = [(2.17+2.50+2.63+3.14+3.23+3.31+3.58+3.62+3.75+3.92)/10]

        =(31.85/10)

      i.e.,   Meam =3.185
