Answer 2

Step-by-step explanation:

(1)Given observations are

78,11,99,63,94,6,78,36,30,55,22

Heighest value =99

Lowest value=6

Range =Heighest value - Lowest value

=>Range=99-6

Range =93

-------------------------------------------------------

(2)Given observations are

20,30,40,10,15,25,35

Writting them into ascending order

=>10,15,20,25,30,35,40

No.of observations =7 is an odd number

If the no. of observations n is an odd then media

is (n+1)/2 th observation

Median=(7+1)/2th observation

=>Median =8/2 th observation

=>Median=4 th observation

Median=25
