The following observations are arranged in ascending order:
20, 23, 42, 53, 2, +2, 70, 75, 82, 96

Answer 1

Answer:

x=61

Step-by-step explanation:

First arranging the numbers in ascending order:-

20,23,42,53,x+2,70,75,82,96

Now,median is 63

>Median M =63

Median M = (n+1)/2 th observation where n is the number of observations

>63=(9+1)/2 th observation

>63=5 th observation

>63=x+2

>x=63-2

>x=61
