Answer correctly I want it argently...​

Answer 1

Answer:

mean = sum of observation/ no of observation

mean=150+155+152+158+154+152+156+154+152/9

= 1383/9 or 1247.88....

first arrange all data in ascending order

150,152,152,152,154,154,155,156,158

median= n+1/2

= (9+1/2)th

=(10/2)th

= 5th

=154 ans

mode=maximum repeating numbers of data= 152

range= highest value - lowest value

=158-150

=8
