Answer 2

Answer:

mean= no. of observations/total no of obervation

         =75+25+45+65+57+20+90+60+43+20/10

         =500/10

mean=50

median =arrange no. into ascending order

             =20, 20, 25, 43, 45, 57, 60, 65, 75, 90

medain is middle no. but there is 10 no. so we will add middle two no. and divide it by 2

=45+57/2

=102/2

=51

mode is 20 cuz it is occuring 2 times
