Question

plz ans 8 and 9 no.extra points​

Answer 1

Answer:

8)x=20

9)x=24

new median is 22.5

Step-by-step explanation:

8) Total 10 observations..which is even hence median is

[(x+1)+(x+3)]/2

given median value is 22

(2x+4)/2=22

2x+4=44

2x=44-4

2x=40

x=20

9)Total observations 10..

given median is 23

(22+x)/2=23

(22+x)=46

x=46-22

x=24

when 32 is replaced by 23 new observations in ascending order are

12,14,17,20,22,23,24,26,28,36

median=(22+23)/2=22.5
