Answer:

36

Explanation:

first arrange them in ascending order

u get 25 28 31 36 40 50 72

we have 7 observations

formula for median is n/2 if it is even n+1/2 if it is odd ( n= no. of observations)

give no. of observations are odd so

7+1/2=8/2=4

therefore 4th observation is our answer

now count from first or from back 4 the observation that is 36 will be our required answer for given problem
