Answer:
mean=75.2,median=72 and mode=72.
Step-by-step explanation:
mean=the sum of all the observations÷the number of observations=(63+72+72+85+84)÷5=376÷5=75.2
ascending order=63,72,72,84,85
the number of observations(N)=5(odd)
median=the {(N+1)÷2}rd observation
=the {(5+1)÷2}rd observation
=the (6÷2)rd observation
=the 3rd observation
=72
The mode is 72,because the frequency of 72 is 2,which is the highest frequency.
