                         Represent this data using a bar graph.
                      3.  The bar graph given alongside shows the marks
                        scored  by  a  student  in  five  different  subjects.
                        Observe the graph and answer the following            100
                        questions.
                                                                               80

                         (b)   In which subject did the student score the    Marks obtained
                             highest marks?                                    40

                         (c)   In which subject did the student score the      20

                         (d)   Arrange the subjects in ascending order of
                             marks scored?                                                      Subjects

                         (e)   What is the scale chosen to represent the
                             marks?
                      4.  The amount (in mg) of a particular medicine given to different patients admitted in a hospital are
                        as follows:

                         160, 130, 142, 150, 135, 190, 142, 160, 142, 174
                         For the above data, evaluate the: (a) mean      (b) median

                      5.  An elevator can carry a maximum weight of 410 kg. A total of 9 people enter the lift. There
                        weights (in kg) are tabulated below.


                             A          B         C          D         E          F         G          H          I

                         (a)  Find the arithmetic mean of their weights.

                         (b)  Find the median of their weights.
                         (c)  If the lift should carry maximum number of persons, who should exit?

                      6.  In a cricket match of 20 overs, the Indian team scores the following runs in the first 8 overs.
                         5, 8, 12, 10, 6, 18, 11, 2

                         (a)  What is the current run rate of the team?

                             (Hint: Run rate is the average run that a team scores in 1 over.)
                         (b)  With this run rate, how many runs can the team score in the match?
