                   14.  Using NumPy package: Create an array of 5 marks and display the average of all marks.

                  Ans.  Program:
                      import numpy as np

                      import statistics
                      a = np.array([95,90,49,71,80])
                      m = statistics.mean(a)
                      print("The average is: ", m)
                      Output:
                       The average is:  77



                   15.  Create a list of distance travelled by a car in a week and calculate using statistics module:
                      •  Mean                 •  Median                  •  Mode
                  Ans.  Program:

                      import statistics
                      d = [95,90,49,71,90,100,55]

                      m1 = statistics.mean(d)
                      m2 = statistics.median(d)
                      m3 = statistics.mode(d)
                      print("The mean is: ", m1)
                      print("The median is: ", m2)

                      print("The mode is: ", m3)
