Step-by-step explanation:

Given The following table shows the distribution of mineral water bottles according to the number boxes. The boxes contains varying number of mineral water bottles. Number of mineral water bottles Number of boxes

   Number of mineral water bottles      Number of  boxes

Class Interval                     Frequency (f)                 Mid Point (x)       f x x

  50 – 55                                         20                            52.5            1050

  55 – 60                                        120                           57.5             6900

  60 – 65                                        105                           62.5             6562.5      

  65 – 70                                        125                           67.5              8437.5      

  70 – 75                                          80                           72.5              5800

                                                       -----------                                         --------------

                                                          450                                              28750

                                               

Therefore Mean = sum of f(x) / sum of f

                           = 28750 / 450

                           = 63.88

So the number of water bottles packed in the boxes will be approximately 63
