Answer:

Mean number of wickets = 153

Step-by-step explanation:

We are given below the distribution that shows the number of wickets taken by bowlers in one day cricket matches;

    Number of wickets          Number of bowlers (f)         X              X*f

           20 - 60                                      7                             40             280

           60 - 100                                     5                            80             400

          100 - 150                                    16                           125            2000

          150 - 250                                   12                           200           2400

          250 - 350                                   2                            300            600

          350 - 450                                  3                            400           1200    

                                                       ∑ f = 45                                 ∑X*f = 6880    

Mean formula is given by = \frac{\sum Xf}{\sum f}        

      Mean = \frac{6880}{45} = 152.88 ≈ 153 .

Therefore, mean number of wickets is 153.
