Answer:
Rearranging the data into ascending order, we get
54,57,59,60,62,62,62,65,70,75,84
Here,
(a) Mean = Sum of observations ÷ number of observations
=
12
54+54+57+59+60+62+62+62+65+70+75+84
=
12
788
=65.6 kg
(b) 4 people have a weight above the mean weight.
(c) Range = greatest observation − lowest observation
=84−54=30 kg
