Answer 1

the given data=80,140,130,150,110,125,130,120,100,130.

Mean=sum of observations/number of observations...........................................................

80+140+130+150+110+125+130+120+100+130/10.=1185/10

=118.5=mean

median=80,140,130,150,110,125,130,120,100,130

=110

mode= highest frequency 130.

hope u can understand this answer.good luck
