                       •    You ask your friends which ‘food item’ they like best. Here is what you found:

                                 Pizza          Burger          Momos            Rolls       French Fries
                                   3               5               6              2               4

                            Create a pie chart of the above data and answer the following questions after studying the graph.
                            •   Which food item is liked most?
                            •   Which food item is liked the least?
                            •   Which food items together constitute 50% of the graph?
                       •    Prepare a histogram of the following distribution on a graph sheet:

                                                        Class interval  Frequency

                                                            10-15          3
                                                            15-20          5
                                                            20-25          6
                                                            25-30          9
                                                            30-35          5

                                                            35-40          4
                                                            40-45          3
                                                            45-50          2
                                                            50-55          1

                            Also mention the kind of peak and skewness that you observe in the graph.
