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 =
Mean = = 152.88 ≈ 153 .
Therefore, mean number of wickets is 153.
