Using the data from exercise 4, calculate the following statistics without importing

(where possible):

a) Mean

b) Median

c) Mode (hint: check out the Counter class in the collections module

of the standard library at https://docs.python.org/3/library/

collections.html#collections.Counter)

d) Sample variance

e) Sample standard deviation
