               5.  Which of the following is NOT a function of statistics module?
                  a. mean()                b. median()            c. floor()            d. mode()
               6.  Which of the following is True about trigonometric functions in Python?
                  a.  They are defined in trigonometry module
                  b. cos() takes a positive integer or floating point number in radians as an input
                  c. sin() takes a positive integer or floating point number in degrees as an input
                  d. tan() returns the arc tan value in degrees.

               7.  Which of the following is false about functions defined in random module?
                  a. random() enables us to generate a random number between 0 and 1.
                  b. randint(p, q) generates random numbers between p and q, both inclusive.
                  c. randrange(p, q) generates random numbers between p and q, both exclusive.
                  d. randrange(p, q) generates random numbers between p and q, only q exclusive.
